Ramp objects should be updated during the game if they have destructables on them

[spudde123]

Some ramp objects may be faulty coming from burnysc2 right now if they have destructables like rocks or small mineral patches on them. Completely blocked ramps don't necessarily even register as ramps, and partly blocked ones can have faulty top_center and bottom_center values and the estimated ramp orientation ends up being incorrect. The commit below fixes this on the map analyzer side by removing destructables first and then redoing the ramp calculation.

The final issue is that now the ramp sides are set to the width without the destructables. Some field in the ramps should be updated during the game to reflect whether the destructables are still there.
