Enhancements

Add QT stylesheets for a more pleasing UI
- The older UI would use the bundled default of PyQt5
- This was OK for Windows, but I really wanted a dark theme for Linux so I found a nice middle ground
- The fonts in this UI were smaller so I had to increase the font size to account for it
Use ruff instead of pylint because it's just faster and better
Freeze all 4th party dependencies
Add Randomize to the class randomizer check boxes to be more apparent at what these check boxes are doing

Bug Fixes

Fix bug where certain prf items would trip the randomizer
Fix bug where Riev was not randomized at all locations and frequently would have a weird on map appearance
Fix several minor item and character randomization misses
Fix bug where dragons in FE6 were randomized to unpromoted units instead of promoted units
- I realized that I don't set Myrrh to a promoted unit
- I'm considering doing that or changing fae to an unpromoted unit for consistency
Fix bug where Roy would no longer be able to seize after promoting
