Tests are failing with new setuptools due to new metadata version #5
Description
The codebase is not ready for a new metadata version, and instead of using the latest mapping available, it falls back to the empty list here:
pkginfo2/pkginfo2/distribution.py
Lines 121 to 122 in 936ccc2
I think it'd be best to use the latest available mapping instead. If this project is still maintained, I'm willing to open a PR.
