This PR adds a new groundmap to the game, Atlan Station.

Atlan Station is an UPP mining platform over a gas giant, partially built into an asteroid. The USS Almayer and her marine complement are answering the automated distress signal of the platform. In lore the platform's responsible for providing Helium-3 fuel to nearby UPP colonies and ships, operating mining skiffs to collect Helium-3 from the gas giant of KG-256 that it orbits and refining it for export. Due to unknown outside forces a mining skiff had picked up a xenomorph egg while in atmosphere and Xenomorphs have attacked the station, resulting in it's distress signal.

Survivors are UPP civilians, workers and reservists. Corporate survivor type includes a Hyperdyne Rep and a CEC Rep- with the CEC rep trading corporate ties for Survivor Scientist skills. CO survivor is that of the Station Administrator, fulfilling a similar skill and loadout to that of the UPP Commissar.

The map has 3 sections; the Hab Ring (dense blocks of housing and residential features, also a promenade), Processing- which houses the refining and export facilities and is housed inside of the asteroid, and general Station facilities- including a drydock for repairs and refuels of the mining skiffs.

Explain why it's good for the game

New maps add variety and longevity to the game, should be fun.
