Package the jupyterlab extension with the Python package

[consideRatio]

As @jtpio describes in #229 (comment), we can package the jupyterlab extension to install automatically as part of installing the python package!

I'd like to work on this, if not taken already!

@dipanjank greatly appreciated! Please mention me for review, I'd like to learn about this procedure :)

Thanks all!

Hi! I'd also like to give this a try. :)

I would suggest to take inspiration from jupytext, where the JL extension has already been packages.

From what I could see I believe you need to

• add a build:prod script to the package.json
• change the setup.py to use jupyter_packaging

Nice, thanks @janjagusch!
