Subject: [PATCH] setup.py: switch import to setuptools

Switch to standard setuptools import, add suggested entries to
pyproject.toml.

Remove the --clean argument.  As the comment suggests I'm sure there
is history here, but having setup.py remove parts of the package does
not seem like something required at this point.

Also clean up the imports to remove unused and group them together at
the top.
