Place all `setup.py` configuration parameters in `setup.cfg`

[Hans-Smit]

The setup.py file will end up looking like this:

"""A setuptools based setup module.

See:
https://packaging.python.org/en/latest/distributing.html
https://github.com/pypa/sampleproject
"""


# Always prefer setuptools over distutils
from setuptools import setup

setup(package_data={"archon": ["py.typed"]})

And the setup.cfg will look something like this:

# See the docstring in versioneer.py for instructions. Note that you must
# re-run 'versioneer.py setup' after changing this section, and commit the
# resulting files.

# Versioneer is for later. See: https://github.com/python-versioneer/python-versioneer
# [versioneer]
# VCS = git
# style = pep440
# versionfile_source = solary/_version.py
# versionfile_build = solary/_version.py
# tag_prefix =
# parentdir_prefix = archon

[bdist_wheel]
# This flag says that the code is written to work on both Python 2 and Python
# 3. If at all possible, it is good practice to do this. If you cannot, you
# will need to generate wheels for each Python version that you support.
