Space sections substantially slower (5-15 sec, exponential) with cooling (#16115)

* Space sections fractionally slower (1 sec, exponential)

- ExplosivelyDepressurize reduces air pressure by about 20% each pass, sets to vacuum below 20 kPa
- Causes some issues with AdjacentBits on airlock close

* Introduced constants for Spacing in atmospherics

* Limit space wind allowed during spacing to 1000 kPa per tile/sec

- Less tile ripping per tick
- Tiles rip based on wind
- Robustness checks

* Slowed down the spacing a bit

* Slowed down the spacing a bit more

* Better dynamics about high pressure air escaping,

- Reduce air temperature (due to decompression) during spacing
- Make some water vapor for flavor

* Limit temperature loss to >8 Deg.C. No Water vapor
