create language bindings for PsycheC's public API

[ltcmelo]

Languages for which bindings are mostly desired:

• [ ] Python
• [ ] Rust
• [ ] Lua
• [ ] OCaml
• [ ] Go
• [ ] C

Perhaps, for all languages that tree sitter has bindings for?

Bindings are expected for the public api, ie, types/methods annotated with PSY_API, PSY_C_API, and PSI_COMMON_API.

For API consistency across languages and productivity, a tool with a common language interface should be used, e.g., SWIG.
