glacier major atmos rework

[deltanedas]

About the PR

completely redone atmos on glacier
instead of mixer -> distro -> air vents, its now (bunch of control devices) -> distro network -> passive vents
it also has some inline filters and , with a new burn chamber for making trit or powerful station heating

air alarms automate oxygen and nitrogen levels and pumping out gas when theres too much pressure. the entire station now actually gets maintained at 21% oxygen so if hyperoxia ever gets added itll just werk for 1 map at least

departments have valves in their substations to cut them off from the distro network for maintenance or if you need to prioritize areas if you didn't make a good heating setup e.g. botany makes frezon so isolate it
the botany one is in botany for when botanists make trit/frezon they can immediately react, the others are all locked in substation rooms

minor stuff

• circuit printer
• minor cleanup of pipes
• autoclave in surgery
• warden hardsuit real

draft until fires and breaches are fully tested to see how it plays out, and if automatic valve closing is needed to deal with them

Why / Balance

i did this ingame before its good, gives atmos something to do so people can stop crying that "nothing ever happens", go make burn chamber powered central heating
passive vents everywhere is a syndies dream but atmos sabotage is against the rules so its fine

Media

automated control pumps

burn chamber replacing the thing that got tore down every round

anti-botany filters

Changelog

• tweak: Massively reworked glacier's atmos system, everywhere on the station has passive vents and is centrally regulated in atmos.
