liminalness

massively overhaul mod backend

• optimize AABB room bound checking, localized to player radius
• optimize schematic connection points to chunk-placements
• improve chunk repairs on ticks limited to only necessary chunks and frontier connection points
• add individual schematic properties to enable infinitely more unique connection points
• add automatic rotational and mirrored variants from one schematic, reducing number of manual schematic files to exist by a factor of 8
• add multi-dimensional datapack support (documentation still needed)
• a whole ton more i genuinely forgot since its been so many things
