Add support for a browser based LaTeX renderer

[psychemedia]

My understanding of jupyterlab-latex is that it currently requires access to a "desktop" Latex rendering application to render tex documents.

This adds to the complexity of setting up a JupyterLab environment by requiring the installation of additional operating system packages, and does not support the in-browser JupyterLite environment.

As JupyterLab/JupyherLite is a browser based environment, it would be useful if an in-browser dependency in the form of a wasm/js LaTeX renderer could be used to render LaTeX/TeX documents, rather than an operating system dependency.

This sounds exciting! Are you aware of any existing examples of wasm/js latex renderers I can look at?

I've just been doing a scout around (a quick demo would probably to be see if the package can be used as a mime-type renderer).

Possibilities might include:

• latex.js (last maintained last year; there is an npm package but I couldn't import from it? Not packaged as a module?)
• SwiftLaTeX (last maintained six months ago; no npm package?)
• unified-latex (MyST seems to use this?)
• busytex ("Programs from TexLive 2023 compiled with Emscripten into a single fully static binary (x86_64-linux / WASM)"
