Add tree-sitter / web-tree-sitter parser

[0xdevalias]

Clear and concise description of the problem

As a developer using ast-explorer, I want to be able to see the AST's parsed by tree-sitter / web-tree-sitter

Suggested solution

It would be really cool if AST Explorer was able to support 'Semantic' and/or 'Tree-Sitter':

• https://github.com/github/semantic

  • Parsing, analyzing, and comparing source code across many languages

• https://github.com/tree-sitter/tree-sitter

  • An incremental parsing system for programming tools

  • https://github.com/tree-sitter/tree-sitter/blob/master/lib/binding_web/

    • WebAssembly bindings to the Tree-sitter parsing library.

  • https://github.com/tree-sitter/tree-sitter/tree/master/cli

    • The Tree-sitter CLI allows you to develop, test, and use Tree-sitter grammars from the command line.

• https://github.com/tree-sitter/node-tree-sitter

  • Node.js bindings for tree-sitter

Tree sitter's WASM distribution seems to be able to create an AST in browser:

npmjs.com/package/web-tree-sitter

I tried web-tree-sitter, but it seems like it cannot be loaded via CDN. There's a path error, which could be caused by tree-sitter itself, and it's even not an ESM module...

About semantic, it cannot run on browsers, I guess.

True true; that sucks :(
