Some hardsuit related ports and changes (#4487)

-adds tajaran sprites to the eva rig, ported from polaris
-ports the emp repair step from bay
-ports the suit cooling unit from bay, with some changes, you can print them from robotics with some tech and materials
-fixes the hand emag module
-vox should not more be able to deploy hardsuits, due to their clearly alien body
