Surveyor Map Framework

Changes:

• Remap invalid block/biome palettes in regions on-load when needed, allowing for safe removals from the registry (e.g. uninstalled biome mods)
• Soft fail when reading outside the bounds of the palette (hopefully this yields more information if the above hasn't already fixed this issue)
