For a tarball like the one at pythonhosted you'd download the file and
then run 'guix hash the-file'. If you're using a source code repository
then from the top level of the repo you'd run 'guix hash --exclude-vcs
--recursive .', or 'guix hash -rx .' for short. The hash layout that
Guix uses is the sha256 of the tarball base32 encoded, but with a change
in the letters used.

For python packages you can specify a version number, so in this case
it'd be 'guix import pypi jupyterlab_server/2.0.0rc1'. Some other
importers us the '@' symbol to specify version number and I think some
don't support using other versions at all.

I don't know how compatible different major versions of
jupyterlab-server are with each other, so I'd stick with 1.2.0 for now.
