Doesn't work with newer Solidity versions

[CodeForcer]

This library is great, but fails to generate valid ABIs on newer versions of Solidity in various ways, ie not marking functions as payable when appropriate.

Any plans to maintain?

@CodeForcer I haven't used it in a while, can you provide a test sample? I'll update the code soon

@CodeForcer can you check this PR? #19 - it should solve some issues with Solidity 0.8+

There might still be some missing cases, I have to finish checking the documentation differences and get more samples.
