Stardew Valley 6.x.x: The Content Update (#3478)

Focus of the Update: Compatibility with Stardew Valley 1.6 Released on March 19th 2024
This includes randomization for pretty much all of the new content, including but not limited to
- Raccoon Bundles
- Booksanity
- Skill Masteries
- New Recipes, Craftables, Fish, Maps, Farm Type, Festivals and Quests

This also includes a significant reorganisation of the code into "Content Packs", to allow for easier modularity of various game mechanics between the settings and the supported mods. This improves maintainability quite a bit.

In addition to that, a few **very** requested new features have been introduced, although they weren't the focus of this update
- Walnutsanity
- Player Buffs
- More customizability in settings, such as shorter special orders, ER without farmhouse
- New Remixed Bundles
