Use node tree-sitter

[selfint]

Last time I checked, it didn't work, maybe now it does?

It does work! But much work has to be done to make it 100% functional.

Maybe instead of using node-tree-sitter, we can use napi-rs and write our own tree-sitter wrapper for node, in Rust instead of CPP?

Works only on Mac and Linux now, once Windows support comes we will switch.

going with web-tree-sitter

It works now, starting migration.

Should resolve #173.
