Away Site Exoplanet Generation Improvements + Crystal Planet and Cryo Outpost Updates (#19735)

changes:
- rscadd: "Crystal Planet Outpost Update. Adds submaps and exoplanet
generation."
  - rscadd: "Cryo Outpost Update. Updates exoplanet generation."
- rscadd: "Away Site Exoplanet Generation Improvements. Allows setting
atmos for all exoplanet turfs on the map."
- rscadd: "Away Site Exoplanet Generation Improvements. Exoplanet turfs
can have light if they are outside."
- rscadd: "Away Site Exoplanet Generation Improvements. Base Turf fixes,
explosions do not turn turfs into space, and destroying or mining turfs
is generally better handled."
