Surveyor Map Framework

Changes:

• Refactor the regional block and biome palettes to be authoritative based on the registry raw IDs
  • This resolves an issue where other mods could flood the palette with duplicate instances of the same biome by mixing into the wrong place.
    • This is bad behaviour anyway, but it's worth having resilience there.
  • The new raw-id-based palettes are strict about registry freeze - they do not resize and will crash when handed a biome registered after world load. We'll see if this needs to be changed when we improve cross-dimension support.
  • Palettes are still exposed as IndexedIterable<Biome/Block> so there shouldn't be any API breakages.
