feat: treesitter highlighter

[folke]

Quick test of a treesitter highlighter for labels.

Should not be merged yet, since it is currently configured as the default highlighter.

Let me know what you think and if this is something you'd like to have in blink.
Maybe disabled by default and under a config flag somewhere?

I'd love something like this in the core! Disabled by default like you suggested, with a config flag in the draw config. Also TIL about get_string_parser, would've made my experiments much easier 😄

I had a few ideas months ago on merging the label with the detail, but you'll need to remove detail from resolveSupport.properties in the LSP capaibilities. It might also be interesting to explore using the kind field for adding brackets (blink.cmp.completion.brackets) to help treesitter get the right highlighting. Here's some messy code I had lying around from that experimenting, iirc with rust-analyzer: https://paste.super.fish/p/pLoiVa.lua

Interesting idea!

I just updated the code to make treesitter highlights configurable and also added a caching layer just in case.
