Give Shaft Miners their own headset with Cargo and Research channels

Because Shaft Miners are basically serving R&D, and Quartermasters don't
want to hear the Roboticist's constant bitching, we now have Mining
Headsets !

- Mining Headset included. Has access to the Cargo and Science channel
and has a special, distinct sprite (darker shade of brown with a small
antenna)
- Added a matching encryption key while using the sprite convention
- Updated Cargo's headset to glorious Cargonia orange instead of shitty
stock white
- Mining headset added to Mining lockers, on spawn on Shaft Miners and
on miner corspes

Fixes #4745

+  - imageadd: Modify the existing and unsued Mining headset and encryption key, and the existing Cargo ones to look more distinct and related to their functions
