Proc-Macros for use in the SUS compiler.

Right now this just contains three proc-macros. kind!, kw!, and field!. They are there to make compile-time queries to the tree-sitter-sus grammar. It's compile-time, requires no runtime queries, and they can be used in more contexts, like match arms.

The grammar is generated using tree-sitter. Used as the parsing front-end of the sus-compiler.

The SUS compiler repository is here.

This package provides bindings for C, C++, and Rust. (And tree-sitter implemented a few more but who's counting. )

In the future I'll probably add macros for derive macros like migrating or collecting Spans
