expose bindings for python

[keewis]

py-tree-sitter somewhat recently had a major breaking release that removed Language.build_library and changed the signature of Language to:

import tree_sitter
import tree_sitter_<lang>

lang = tree_sitter.Language(tree_sitter_<lang>.language())

which means that using tree-sitter-rst from python requires language bindings.

If you merge the PR we'd have to publish to tree-sitter-rst on PyPI, which is currently published from py-tree-sitter-rst (cc @Carreau).

In this PR I've copied / adapted the binding implementation from tree-sitter-python, which works but may not be the most elegant. In particular, I had to include all the files that are usually auto-generated by tree-sitter from grammar.js (and any other requires files) in the sdist. Maybe it would be better to call tree-sitter build / tree-sitter generate while building the wheel instead?

tree-sitter also appears to have moved its configuration from package.json to tree-sitter.json, so this is included in the PR. If you prefer a smaller PR I can definitely move all of the automatic changes to a separate PR.

Happy to give access to Pypi if someone wants it.

Hi, sorry for replying late, I'll try to review it this weekend.

Nice! I'll may be able to setup an action to publish to pypi. I'm stsewd on pypi.
