Precompile .wasm parsers

[selfint]

Use workflow_dispatch and write a workflow that:

• Downloads the parser with npm
• Builds the .wasm parser
• Uploads the parser as an artifact

This way the clients don't need to have tree-sitter installed, and so also not emcc or docker.

Or, simply precompile all parsers on a weekly schedule.

Finally, how bad is it really to package all the parsers inside the extension?

Terrible

This is the way to go though, since an internet is connection is required for it to work anyway, this just means they don't need to install emscripten.

This option can also be opt-in. A choice popup can let the user choose to download prebuilt or to build locally.

Maybe implement like this:

1. Use npm api to get latest version of parser.
2. Check if that version has a pre-compiled parser.
3. If not, call the pre-compile task and wait for it to complete.
4. Download the parser.

This is irrelevant now that #125 is working.
