Highlights

• syn-solidity is now (almost) complete, as it can also parse all expression, statements, and Yul. Special thanks to @Will-Smith11, @mouseless-eth, and @0xMemoryGrinder! (#314, #268, #199)
• alloy-json-abi items (like Function and Event) can now be used in combination with alloy-dyn-abi to ABI-encode their input or output parameters through JsonAbiExt (#243)
• All the encode, encode_single and functions and their respectives in decode* and SolType::* were renamed to encode_sequence and encode respectively. *_params functions remain unchanged (#274)
• Prefixed all ABI encode and decode-like functions with abi_; alloy-sol-types ABI-related items were moved into the abi module (#311)
• alloy-sol-type-parser got 10% to 50% faster, but now rejects any whitespace (#292)
• Lots of bugfixes
