ERC20SignatureMint

The ERC20SignatureMint smart contract adds the signature-based minting extension functionality to the ERC20Base contract. Signature minting uses EIP-712, which enables the contract admin to authorize an external party's request to mint tokens on the admin's contract. At a high level, this means you can authorize others to mint tokens on your contract, and specify what exactly will be minted by that external party.
