       * accounts that have a role's admin role can call {grantRole} and {revokeRole}.
       *
       * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
       * that only accounts with this role will be able to grant or revoke other
       * roles. More complex role relationships can be created by using
       * {_setRoleAdmin}.
       *
       * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to

      /**
       * @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
       * behind a proxy. Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an
       * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
       * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
       *
       * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be
       * reused. This mechanism prevents re-execution of each "step" but allows the creation of new initialization steps in
       * case an upgrade adds a module that needs to be initialized.
       *
       * For example:
       *
       * [.hljs-theme-light.nopadding]
       * ```solidity
       * contract MyToken is ERC20Upgradeable {
       *     function initialize() initializer public {
       *         __ERC20_init("MyToken", "MTK");
       *     }
       * }
       *
       * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {
       *     function initializeV2() reinitializer(2) public {
       *         __ERC20Permit_init("MyToken");
       *     }
       * }
       * ```
       *
       * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
       * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.
       *
       * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
       * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.
       *
       * [CAUTION]
       * ====
       * Avoid leaving a contract uninitialized.
       *
       * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation
       * contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke
       * the {_disableInitializers} function in the constructor to automatically lock it when it is deployed:
       *
       * [.hljs-theme-light.nopadding]
       * ```
       * /// @custom:oz-upgrades-unsafe-allow constructor
       * constructor() {

           * - When `from` and `to` are both non-zero, `amount` of ``from``'s tokens
           * of token type `id` will be  transferred to `to`.
           * - When `from` is zero, `amount` tokens of token type `id` will be minted
           * for `to`.
           * - when `to` is zero, `amount` of ``from``'s tokens of token type `id`
           * will be burned.
           * - `from` and `to` are never both zero.

       * @dev https://eips.ethereum.org/EIPS/eip-712[EIP 712] is a standard for hashing and signing of typed structured data.
       *
       * The encoding specified in the EIP is very generic, and such a generic implementation in Solidity is not feasible,
       * thus this contract does not implement the encoding itself. Protocols need to implement the type-specific encoding
       * they need in their contracts using a combination of `abi.encode` and `keccak256`.
       *
       * This contract implements the EIP 712 domain separator ({_domainSeparatorV4}) that is used as part of the encoding
       * scheme, and the final step of the encoding to obtain the message digest that is then signed via ECDSA
       * ({_hashTypedDataV4}).
       *
       * The implementation of the domain separator was designed to be as efficient as possible while still properly updating
       * the chain id to protect against replay attacks on an eventual fork of the chain.
       *
       * NOTE: This contract implements the version of the encoding known as "v4", as implemented by the JSON RPC method
       * https://docs.metamask.io/guide/signing-data.html[`eth_signTypedDataV4` in MetaMask].
       *
       * NOTE: In the upgradeable version of this contract, the cached values will correspond to the address, and the domain
       * separator of the implementation contract. This will cause the `_domainSeparatorV4` function to always rebuild the
       * separator from the immutable values, which is cheaper than accessing a cached version in cold storage.

       * Sets have the following properties:
       *
       * - Elements are added, removed, and checked for existence in constant time
       * (O(1)).
       * - Elements are enumerated in O(n). No guarantees are made on the ordering.
       *
       * ```solidity
       * contract Example {
       *     // Add the library methods
       *     using EnumerableSet for EnumerableSet.AddressSet;
       *
       *     // Declare a set state variable
       *     EnumerableSet.AddressSet private mySet;
       * }
       * ```
       *
       * As of v3.3.0, sets of type `bytes32` (`Bytes32Set`), `address` (`AddressSet`)
       * and `uint256` (`UintSet`) are supported.
       *
       * [WARNING]
       * ====
       * Trying to delete such a structure from storage will likely result in data corruption, rendering the structure
       * unusable.

       * array of EnumerableSet.

       * Roles can be granted and revoked dynamically via the {grantRole} and
       * {revokeRole} functions. Each role has an associated admin role, and only
       * accounts that have a role's admin role can call {grantRole} and {revokeRole}.
       *
       * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
       * that only accounts with this role will be able to grant or revoke other
       * roles. More complex role relationships can be created by using
       * {_setRoleAdmin}.
       *
       * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to
       * grant and revoke this role. Extra precautions should be taken to secure

      /**
       * @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
       * behind a proxy. Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an
       * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
       * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
       *
       * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be
       * reused. This mechanism prevents re-execution of each "step" but allows the creation of new initialization steps in
       * case an upgrade adds a module that needs to be initialized.
       *
       * For example:
       *
       * [.hljs-theme-light.nopadding]
       * ```solidity
       * contract MyToken is ERC20Upgradeable {
       *     function initialize() initializer public {
       *         __ERC20_init("MyToken", "MTK");
       *     }
       * }
       *
       * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {
       *     function initializeV2() reinitializer(2) public {
       *         __ERC20Permit_init("MyToken");
       *     }
       * }
       * ```
       *
       * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
       * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.
       *
       * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
       * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.
       *
       * [CAUTION]
       * ====
       * Avoid leaving a contract uninitialized.
       *
       * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation
       * contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke
       * the {_disableInitializers} function in the constructor to automatically lock it when it is deployed:
       *
       * [.hljs-theme-light.nopadding]
       * ```
       * /// @custom:oz-upgrades-unsafe-allow constructor
       * constructor() {

       * @dev https://eips.ethereum.org/EIPS/eip-712[EIP 712] is a standard for hashing and signing of typed structured data.
       *
       * The encoding specified in the EIP is very generic, and such a generic implementation in Solidity is not feasible,
       * thus this contract does not implement the encoding itself. Protocols need to implement the type-specific encoding
       * they need in their contracts using a combination of `abi.encode` and `keccak256`.
       *
       * This contract implements the EIP 712 domain separator ({_domainSeparatorV4}) that is used as part of the encoding
       * scheme, and the final step of the encoding to obtain the message digest that is then signed via ECDSA
       * ({_hashTypedDataV4}).
       *
       * The implementation of the domain separator was designed to be as efficient as possible while still properly updating
       * the chain id to protect against replay attacks on an eventual fork of the chain.
       *
       * NOTE: This contract implements the version of the encoding known as "v4", as implemented by the JSON RPC method
       * https://docs.metamask.io/guide/signing-data.html[`eth_signTypedDataV4` in MetaMask].
       *
       * NOTE: In the upgradeable version of this contract, the cached values will correspond to the address, and the domain
       * separator of the implementation contract. This will cause the `_domainSeparatorV4` function to always rebuild the
       * separator from the immutable values, which is cheaper than accessing a cached version in cold storage.
