Full Ethereum JSON-ABI implementation.

This crate is a re-implementation of a part of ethabi's API, with a few main differences:

• the Contract struct is now called JsonAbi and also contains the fallback and receive functions
• the Param and EventParam structs only partially parse the type string instead of fully resolving it into a Solidity type

Parse a JSON ABI file into a JsonAbi struct:

use alloy_json_abi::JsonAbi;

# stringify!(
let path = "path/to/abi.json";
let json = std::fs::read_to_string(path).unwrap();
# );
# let json = "[]";
let abi: JsonAbi = serde_json::from_str(&json).unwrap();
for item in abi.items() {
    println!("{item:?}");
}
