ERC1155 Signature Mint

The ERC1155SignatureMint smart contract uses the ERC1155Base base contract along with the SignatureMintERC1155 contract extension.

The 'signature minting' mechanism in the SignatureMintERC1155 extension 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.
