Remaining items missing sound effects now have sounds assigned. That's the sabatier reactor, electrolyser, distillery, sewage treatment, armory and casino. I've also added sounds for humans when they are sleeping or using bathroom. Possibly a few more sfx to add, but now much better.

Also fixed a couple of issues with the sewage treatment item, it wasn't removing used waste / air and tracking created compost correctly,

Patch notes:-

• Sounds added for Sabatier, Electrolyser, Distillery, Sewage, Armory and Casino items.
• Sounds added for humans using bathroom/sleeping.
• Fix: Sewage treatment not removing waste/air correctly.
• Fix: Sewage process not tracking created compost correctly.
