Make WASM builds

[CetinSert]

difftastic would benefit greatly from wasm builds! It would open the project up to web browsers, deno deploy, bun oven, cloudflare workers!

I'm open to PRs for this. The fiddly bit is getting the tree-sitter parsers compiled to wasm, as they're C code.

This will be a great feature.

I just found that actually the underlying tree-sitter had have a WASM version for years. Please check https://github.com/tree-sitter/tree-sitter/blob/master/lib/binding_web/README.md

So, is it possible to build WASM version of Diffastic?

BTW, on web a Markdown display for code will be better than a direct HTML display.

Thank you in advance,

Hi @Wilfred

I wanted to understand what is the feasibility of doing this given that tree-sitter has a WASM based version (https://github.com/wasm-lsp/tree-sitter-wasm). Also, if you can attach any comprehensive GitHub comments, or guides to build this it would be helpful.

Thanks!
