V0.6.1: Final version without wall observations

Depreciation Note

This is the final version that is still compatible in terms of tensor shapes for state observations with models trained as described in Gym-μRTS paper.

After this version, we are going to add an extra channel to state observations representing the terrain (whether or not there is a wall on any given cell), which means that models trained for the old code will be incompatible because they'll be receiving larger input tensors than they expect.
