v2.0.0 - Glimmwood Authentic Tea Edition

What's Changed

There's so much new stuff that I'm struggling to remember it all! I accidentally forgot to make a release for v1.2.1 so that's all bundled in here as well.

• Fix Symbol generation and add support for Hidden spawns. Marked shiny authentic Glimmwood Sinistea is now an achievable dream! Huge thanks to @Elvis0077 and @zyro670 for testing, and congrats to you both on your teas!
• Add DaySkip (requires @Koi-3088's Hybrid BotBase) and Wild Encounter Reader for CFW users (thanks @zyro670!)
• GUI Updates to accommodate the above.
• Modernize project style (thanks @Lusamine and @kwsch!) and bump .NET version to 6.0.
• Begin to modularise and restructure the repo (and add unit tests!)

Originally this was only going to be a minor version bump, but I figured that fixing Symbols/Hiddens was significant enough to warrant 2.0.0. Have fun!
