Release as python package

[bollwyvl]

npm is getting the business done in the browser, but can't bring it home to handle the rest of the lifecycle of using jyve.

While a pypi wheel will still suffer from the two (three? n?) package manager problem, it's the first step towards making jyve a more usable thing.

A subsequent conda package offers a complete solution for the current capabilities, with the ridiculously glaring exception of an actual browser.

steps/decisions

some of these probably need their own discussion issue....

• [ ] validate current packaging setup
• [ ] documentation
• [ ] code cleanup
• [ ] decide what gets automatically installed
  • [x] the nbconvert "fake lab" exporter
  • [ ] a single-html, plain html nbconvert exporter
  • [ ] a labextension tarball exporter?
  • [ ] a wrapper jupyter jyve (nbconvert|lab) application?
  • [ ] tests?
  • [ ] real kernelspecs?
  • [ ] labextensions
  • [ ] with data_files?
    • [ ] @deathbeds/jyve-extension
    • [ ] @deathbeds/jyve-js-unsafe-extension
    • [ ] @deathbeds/jyve-typescript-unsafe-extension
    • [ ] all the kyrnels
    • [ ] all the lybs
  • [ ] an alternate, pre-built app_dir
• [ ] automate pypi deploy with twine, etc.
  • would mostly automate the conda-forge process via bot
• [ ] automate documentation deploy with readthedocs, etc.
