Deploy to PyPI, install with pip; removed some vulnerabilities…and more!

[nutjob4life]

Purpose

Merge this PR and get some vulnerabilities removed, PyPI support, and you can pip install slim-leaderboard once this is published to PyPI.

Proposed Changes

• Removal of unbounded dependency confusion vulnerabilities
• Addition of PyPI project metadata
• You can pip install it!
• Removal of unused imports
• Application of basic PEP8 formatting
• Unapologetic removal of commented-out code that lacked comments explaining why it was commented out (yes, a personal pet peeve)
• Removal of infused_count = pr_count = issue_count = total_count = 0 as these variables were never used
• Support for --version

Issues

No issues; I just wanted to be able to pip install this and saw opportunities for additional fine-tuning.

Publishing to PyPI

Well, we have @ingyhere's new trusted publishing support, but for a quickie:

$ python3 -m build
$ twine upload dist/*

And make sure to add the appropriate collaborators.
