Push up to support Python 3.9.13, bump everything

[aersida]

Description

Primary objective - get WebControl working with Python 3.9+ on anything.

Apologies - I ran black and there's a lot of reformatting, some of the reformatting I reversed out so that there's less code to review. But even so, I figured some of the blackening can be left in.

The Big (and little) Changes

• Identifying package dependencies in each folder - see requirements.in in most folders
• Referencing those dependencies in the 'root' requirements.in
• Using pip-compile (from pip-tools) to completely rebuild the requirements.txt, pinning everything that gets imported (not just some things), and hopefully the specific versions of everything that will work well together.
• Cleaning up imports in many files, eliminating imports that are unused
• Fixing that monkey.patch_all problem in main.py
• Significant rewrite of the virtual environment section of the README
• Adding a little hack to ReleaseManager.py so it can handle tags that don't look like floats (look for release_tag_map in the code)
• Some restructuring of certain strings to use the f"Your variable here: {v}" format
• Dropping flash_misaka - just can't be upgraded
• Replacing wget with requests - wget is completely gone as a package (can't be built from source as there is no source anymore)
• Dropping six - just not used

Recommendations

• Get rid of holeyrequirements.txt - it should be surplus to requirements now (pun intended)
• Add some info on how to build the executable

Testing

Yes please
