Backrooms PBR / Poolrooms PBR

Major overhaul to the project, changed all of the wallpapers and fixed their scaling to be correct with real life porportions of how they really are, if you don't like this change, take it up with me in the feedback channel in the discord server.

changed codenames for pool tiles, now it should also display slab and stair variants

standardized most of the blocks to be 1024x to improve performance and negate memory leaking
