ERC20 Signature Mint

The ERC20SignatureMint smart contract adds signature-based minting functionality to the the ERC20Base contract.

Signature minting uses EIP-712, and is a way for a 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 some external party to mint tokens on your contract, and specify what exactly will be minted by that external party.
