Add atmos time compression

[Partmedia]

About the PR

Add atmos.speedup which is effectively a atmos-only time compression CVar. This adjusts heat capacities and transfer rates to effectively globally speed up the time constants of atmos.

This allows faster response to heating/cooling changes and faster cleanups (by buffing scrubbers, pumps, and everything else) that is tunable through one global time compression CVar. It also achieves this without any thermodynamic unsoundness.

And if anyone complains, this number can be increased/decreased as needed without fear of breaking anything.

Why / Balance

Multiple people complained that atmos is too slow/not useful/not fun.

Atmos variables were balanced based on real specific heat capacities and semi-realistic transfer rates. However, things typically happen too slowly in real life for people to feel like they're having fun in a game. See: space-wizards/docs#78

It is also not okay to globally buff all numbers, because:

• That breaks thermodynamics, leading to infinite power via the TEG (and other inconsistencies)
• Every time you go buff all the numbers there is an incredible amount unnecessary repository churn
• It is easy to buff one number and forget to buff all the related numbers

Technical details

• Adds a atmos.speedup CVar. It is used in two ways:

  • As a divisor to the Atmospherics heat capacity function to calculate heat capacity. Setting this to 1 is a "no-op". Setting this to something greater than 1 globally reduces heat capacity, which makes heating/cooling happen faster without breaking thermodynamics. All atmos reactions have their heat output scaled by this same rate to keep the time constant for reactions (e.g. plasma fires) as before so that fires don't burn hotter, because people want all the benefits of time compression without the disadvantages.
  • Multiplies transfer rates by sqrt(atmos.speedup) (via the new AtmosphereSystem.PumpSpeedup() function)

• Teach all the atmos devices that used MaxTransferRate (or derived variables) to multiply by the new PumpSpeedup().

Media

Atmos techs who respond to a gas leak by turning on widenet can now fix problems in a reasonable amount of time. Note that things are still kind of slow if you don't send an atmos tech to go deal with the problem.

Changelog
🆑 notafet

• tweak: Pumps, vents, scrubbers, and heaters now work faster.

turning on widenet 

air alarms do this automatically

Adding do not merge for now since this also makes producing frezon way too fast.

[deltanedas]

just make spacing fast again

[Partmedia]

Since frezon prices were just set to zero, and since there are a few frezon adjustments in the pipeline, I plan to merge this soon. If there is too much fallout the atmos.speedup CVar can be tweaked anywhere between 1–64.
