Feature Request: Improved Solidity Syntax Highlighting

First off, I want to say that this tool is amazing and literally the only thing like it I can find. Thank you for your work on this.

The current Solidity syntax highlighting is very incomplete and in some ways it's quite wrong (e.g. highlights type declarations on parameters in different colours).

Is there something I can find to make it easier to improve the syntax highlighting for Solidity in this program (e.g. a vscode extension which handles Solidity syntax highlighting?), or is the syntax highlighting format that this codebase uses a custom format?

I'd like to try and help make this request easier if it means I can be asked to go and find something and provide it, but it would be awesome if the Solidity syntax highlighting could be improved.

Kindest Regards, Jay
