[WIP] Atmos is back

[stilnat]

Summary

PR introducing atmos back to the game, based on @henkhooft rework to work with the job system and expanded upon.
Still early work as I need to do some more optimisation and to include a few atmos devices.

• Atmos env works with active flux (based on pressure differences) and diffusion (based on moles differences)
• Atmos pipes work in a way similar to TG, when injecting gas into a set of connected pipes (a pipenet), all pipes divide the injected gas equally between them.
• Adding or removing pipes modify pipenets.
• Scrubbers work in siphoning and scrubbing modes.
• Air vents work in pump and suck mode, able to pressurize using internal or external pressures.
• Airlocks keep air from flowing when closed, leave air flowing when opened.

PR checklist

• No unrelated changes are present.

• No "trash" files are committed.
