Make description attribute static

Hmm, seems the description can't be read from an attribute, why? Anyway,
it's not like it changes often. Lets copy it, and add a note to change
the python code to read from importlib.metadata, if we even want to?

TODO:
* compare the output file-by-file of pip install -e before and after
* compare the output file-by-file of setup.py install/build/wheel or
  whatever and the corresponding build commands (and update makefile)
* think about removing stuff that isn't used from `__init__.py`, or
  making it read from importlib.metadata
* see how it looks with hatch (dynamic bits and build hooks)
