adjust run time dependencies

[tacaswell]

importlib-metadata is currently an unconditional dependency, but it is only required for python < 3.8.

Does CF still support older versions of Python and if not can we just bump the minimum supported version of the whole package to be above py38?

I don't know about CF, but Python 3.7 is nearly EOL (in June: https://devguide.python.org/versions/), so we'll be dropping it upstream in https://github.com/python-humanize/humanize/ around that time.

This is a trick to make the package noarch. When we drop py37 we can drop this workaround and keep it noarch. BTW, it is mostly harmless to install importlib-metadata in py>=38, the standard lib one is used.

OK, I'm going to close this and let nature take its course.

Sorry for the noise.

Looks like CF can drop 3.7 now?

2022-08-24: Dropping Python 3.7

Conda-Forge has been providing support for Python 3.7 for 4 years now. Increasingly projects are moving off it (particularly in the PyData community). With Python 3.11’s release coming around the corner (October 3rd), conda-forge plans to drop Python 3.7 support when Python 3.11 comes out. This will lighten the load on conda-forge infrastructure and make room for the new versions the community would like to support.

More details can be found in issue conda-forge-pinning-feedstock#2623. Feedback is welcome there.
