A significant amount of influence was taken from
https://github.com/Baystation12/Baystation12/pull/33255, however adapted
to Aurora. Key things to note is the port of the newer alpha settings
from /tg/, among other improvements.
The ancient holographic and screen overlay code has been purged. This is
now handled with emissives, while holograms are handled with filters as
well.

Adds new sprites for sterile mask and breath masks.
Adds new colorable cloth mask for civillians and dust mask mostly for industrial jobs.
Masks have been move to their own tab in loadout - namely because they have an entire seperate file for them, but apparently haven't been coded in their own tab. Also, they should equip properly on spawn now.
