Shuffler doesn't respect blocked doors yet so it may create an unbeatable layout, and the item placer will panic. But that's better than silently giving the player something impossible
Fixed graphics between HC/Sewers and cross dungeons.
Added base work for spiral staircases in HC/Eastern. (More data needed for other dungeons.)
Added new region to deal with push blocks in Sewers Secret Room
Refactored asm to be in multiple files.
Bug with doors with offset 2 going to doors with offset 2 was fixed in asm.
Refactor asm code to use Y as 2nd index, which cleaned up code.
Also learned the phb:phk:plb ... plb trick (cleaner than what I was doing)
ASAR asm patch included with test tables.
Eastern and Hyrule Castle regions created from a while ago.
Currently broken because boss prizes are unreachable.
