Jupyter Widgets

[jtpio]

Prior work: jupyterlite/jupyterlite#141

• Support comms
• Provide base widgets like the ones from ipywidgets

Preview: https://jupyterlite-javascript-kernel--24.org.readthedocs.build/en/24/lab/index.html?path=widgets.ipynb

Later could be extracted to its own reusable and independent package.

Maybe this can be incubated here for now and moved to a separate package after: #25

Yeah, maybe as a partial step, putting the new stuff in subdirectories, e.g. comm/ and widgets/ would make it quack a little bit more like a package. the widgets file is pretty long, and might benefit from being split up anyway, with parallel structure closer to the py/js dom upstream file names to make it easier to track what has been ported.
