Updated the map, with major changes, the most major being...

-Made the map actually playable. Yeah, kinda important tbh. Some logic went wrong... I'd prefer not to talk about that.
-Removed major sightlines with elevator shaft
-Added elevator shaft
-Made ramps have better geometry.
-Completely reworked the large flank room to have more entrances and exits.
-Created new flank.
-Made the upper floor more closed and interesting.
-Marked out clearly the capping area.

-Also afterwards got rid of pesky leaks.
