Better Toxins Lab

Reworked Toxins Laboratory
- Slightly larger, and burn chamber is less likely to damage adjacent areas.
- Instead of filtering/extracting gas, heat exchangers are used.
- Toxins lab is mostly about heating/cooling gases now. Limited mixing is available too (still more possibilities than old toxins which didn't allow almost anything besides burning gas.
- Also adds fire supression system (sprinklers). Sprinklers are button controlled. Currently mapped into the burn chamber to allow extinguishing of fire before it melts the walls.
