JupyterLab 3 support?

Hello, and thanks for this marvelous tool.

I’d very much like to see this up and running in JupyterLab 3… it constitutes something of a hard break, as the primary distribution would be via only pip install (though nice devs also continue to publish to npm, so that others can extend their stuff). The benefits for users are very significant: no more runtime nodejs, mysterious downloads of 100s of MiB from npmjs.org, a single source of version truth per package, etc. The development workflow is a little weird, more like the nbextension, as it relies on data_files to put stuff in a place on disk, but being able to build once on linux, and test built wheels/sdist everywhere else is priceless.

Happy to help in any way I can!

@bollwyvl Fixed embedding and notebook support and published 2.0.0. I think the issue came from overwriting the package.json file during the JL2 -> JL3 migration. I lost webpack and other stuff for ipywidgets.
