Misc Atmos Improvements (#5613)

* Revert "Remove atmos archiving."

This reverts commit 7fa10bd17b.

* Explosive Depressurization now brings tiles down to TCMB.

* Tiles now specify heat capacity.

* Do not serialize archived gas mixture values.

* Remove bad idea

* dumb typo

* Space gas mixtures now have a harcoded heat capacity.
This is a bit of a hack, but rooms exposed to space now cool down properly when monstermos is disabled.
Huge thanks to @LemonInTheDark for helping me with this!

* Clean up heat capacity methods

* Better logging based on the original monstermos' logging

* Comment explosive depressurization hack better
