Consider packaging and distribution on conda-forge

[matthewfeickert]

In addition to publishing distributions on PyPI, it would be very nice to also distribute on conda-forge and as nflows is a pure-Python package that would be technically easy.

However, given the required dependencies

nflows/setup.py

Lines 20 to 27 in 3b122e5

	install_requires=[
	"matplotlib",
	"numpy",
	"tensorboard",
	"torch",
	"tqdm",
	"umnn"
	],

umnn is not yet on conda-forge and would be required to be distributed there first.

Ah, seems that https://github.com/AWehenkel/UMNN is unmaintained research software so getting https://pypi.org/project/UMNN/ on conda-forge might take some additional work. There might be hope though given that there were releases on PyPI as new as a year ago (December, 2023). Ping @AWehenkel in the event they can offer help (also hello again!).
