EIP-4973 - Account-bound Tokens

[TimDaub]

Updates to the specification and reference implementation

• Removed EIP-2098 support as EIP-1271 expects a “naively” concatenated signature and not an EIP-2098-style compact signature. This was pushed upstream with @frangio removing support for EIP-2098 in the SignatureChecker library.
• Change string tokenURI in structure data hash and give and take inputs to a more generic bytes metadata. PR: Use opaque metadata by frangio · Pull Request #52 · attestate/ERC4973 · GitHub
• Start using forge fmt for all Solidity code formatting
