[MAP/BOX] Addition of AI Satellite + Grav Gen/Upload being moved V2

For reference: https://github.com/tgstation/-tg-station/pull/3423

I can't really easily solve map conflicts. Yeah.

------
What does this add?

The addition of a self contained off station Satellite, primarily used to house the station AI in a far more defensible location. It's secondary usage is a possible location for a back up Telecommunications centre, however the equipment is not built and online.

The satellite runs of its own power and atmo system, the only connection point to the station is via a transit tube connecting to Engineering near the Engi Escape Pod. All Heads and Engineers have access to the satellite, Only the Captain and RD have AI Access and only the Captain and CE have Telecomm access.

DEFENCES
The Satellite houses a more wider array of defences to hold out against intruders, a satallite bound securitron unit, Officer Pingsky, serves as the gate keeper at reception. The exterior is surrounded by Grilles, Walls and Motion Sensor Security Cameras. Standard AI Core defences are in play.

IN ADDITION
Due to the AI Core now being vacant, the Gravity Generator and the AI Upload have been relocated and rearranged, images speak better than words on this.
