Rover Control in AresSim

Tensor Fiend tested Jev on the AresSim environment and described the Rover's movements through the first 50 steps as great. The result was on par with Masked PPO the author had trained earlier.

Tried Jev from @typesafeai on AresSim environment. Overall the Rover's movements until first 50 steps was great. Had to tweak the rules abit to get it work. But it did a decent job (on par with Masked PPO I trained earlier). Making the State form more efficient would also make Jev work better,
