migrate setup.py to setup.cfg

[deronnax]

Setuptools recommends to use declarative setup.cfg over custom imperative setup.py (especially that this one grown some significant body hair)
On the other hand, using data_files (that is used here for man pages) is deprecated and has no direct equivalent in declarative package definition, be it setup.cfg or pyproject.toml, so we might just not be able to replicate the thing.

@deronnax thanks for the PR! If we find a way to maintain full compatibility including data files, I’ll be happy to merge it.

[deronnax]

Sorry, I was wrong, it's actually doable. There you go. Don't forget to squash merge.
Btw, it probably won't be doable with pyproject.toml, but that's a subject for another day.

@deronnax thanks!

It looks like the conditional Windows-only stuff like the colorama dependency has not been ported to the new setup.cfg. Tests pass because pytest depends on colorama as well I beliece.

cli/setup.py

Lines 44 to 63 in 3524ccf

	install_requires_win_only = [
	'colorama>=0.2.4',
	]
	# Conditional dependencies:
	# sdist
	if 'bdist_wheel' not in sys.argv:
	if 'win32' in str(sys.platform).lower():
	# Terminal colors for Windows
	install_requires.extend(install_requires_win_only)
	# bdist_wheel
	extras_require = {
	'dev': dev_require,
	'test': tests_require,
	# https://wheel.readthedocs.io/en/latest/#defining-conditional-dependencies
	':sys_platform == "win32"': install_requires_win_only,

oops sorry. Actually that's tox that's depending colorama.
