pip-licenses broken in python 3.11

[b-kamphorst]

pip-licenses is broken in python 3.11 for pip>=22.1.

The issue is roughly the same as in #113. Log:

$ pip-licenses

https://github.com/raimon49/pip-licenses/pull/116 attempts to solve this issue with setuptools. I'm no expert, but perhaps importlib.metadata can be considered (built-in)?

A release candidate version that works well with Python 3.11 is available thanks to bart's contribution. https://pypi.org/project/pip-licenses/4.0.0rc1/

Users who wish to try this version before the official release should install it with pip.Feedback on running it in different environments is welcome.

$ pip install 'pip-licenses==4.0.0rc1'

@raimon49 I just opened this issue and your comment popped up a few seconds after :)

I installed the rc1 and this works for me on 3.11.

[raimon49]

RC2 is now available following bug reports and patches. #132

pip install 'pip-licenses==4.0.0rc2'

We continue to welcome feedback.
