Implement Space EVA

[Niker25]

This PR adds Deep Space EVA and Apollo 9 EVA (CSM/LM)

EVA Deployment conditions
-CSM: Crew = 3 (in PAMFD) and the side hatch opened
-LM: Apollo 9 mission, LMP in PLSS and forward hatch opened

Both EVAs are initialized with "EVA" button in PAMFD

-EVA Termination: put the astronaut inside the vehicle and press key "E"

What about the conditions for Apollo 9 CSM EVA? Should be something like checking for the hatch and crew 1?

Also you might need more safety checks for the deep space EVA to prevent an EVA on the pad for instance by accident.

The conditions are Side hatch open and Crew = 3 in cabin (for CMP in cabin mesh deletion).
The EVA code is in saturn (CSM) code not in Saturn V code, therefore, until Saturn is in orbit, the EVA cannot be performed

Crew will equal 1 in the CSM for Apollo 9 EVA, so this doesnt work

Crew number condition deleted. Now Apollo 9 EVA works as expected
