Cursorless Tree sitter wasms

Repository building wasms for use by Cursorless.

Instructions for adding new parser wasms (WIP):

1. Add the tree-sitter package for the specific language to devDependencies in package.json directly, or use npm install --save-dev --ignore-scripts <package>.

2. Bump minor version in package.json

3. Run npm install --ignore-scripts to update package-lock.json.

• If a build failure of some sort occurs, you will need to utilize the special build options in build.ts, specifically in the processParser function. If you can't figure it out, leave the PR as a draft and ask for help.
