Removed legacy store, fixed sewer z fight, removed maw (trying to fix missing npcs)

everything unlocks 5 waves earlier increased Zhen multiplier from 1 to 3

Attempted to fix doors to minimise npcs going stray. Added some plasma ammo, lowered unlock wave for Lab 2 (25) and Mech (30)

changed armoury in an attempt to stop rogue npcs from passing through and causing a soft lock.

Deleted an extruded voxel that came from nowhere. And fixed up the tape.png a little.
