Erc721WithQuantitySignatureMintable
Enables generating dynamic ERC721 NFTs with rules and an associated signature, which can then be minted by anyone securely

Generate a signature that can be used to mint a dynamic NFT
Takes in an NFT and some information about how it can be minted, uploads the metadata and signs it with your private key. The generated signature can then be used to mint an NFT using the exact payload and signature generated.
