[Post] MultiHashWraper

Options:

• store bytes representation without splitting
• split using abi.decode()
• split using assembly
• pass in as separate params

For the first 3 options, it would be worthwhile to perform input validation by checking the length of the bytes field

Option 2:

    function _combineMultiHash(MultiHash memory multihash) internal pure returns (bytes memory) {
        return abi.encode(multihash.hashFunction, multihash.digestSize, multihash.hash);
    }

    function _splitMultiHash(bytes memory source) internal pure returns (MultiHash memory) {
        (uint8 hashFunction, uint8 digestSize, bytes32 hash) = abi.decode(source, (uint8,uint8,bytes32));
        return MultiHash(hash, hashFunction, digestSize);
    }

For now, split using assembly and source length validation
