Robot Masters get stuck in walls easily

If Airman jumps into the ceiling, he can get temporarily stuck.

In Woodman stage, Quickman spawns in the ceiling, but falls out immediately.

In Woodman stage, Metalman spawns in the ceiling and stays there.

In Woodman stage, Bubbleman gets stuck in the ceiling until you get up to his y-pos. Also high movements during the fight can get him stuck in the top-right.

In Quickman stage, Heatman may get stuck in the wall (verify)

Mitigated due to various edits to robot master rooms and tweaks to AI parameters. BubbleMan can still get stuck in some walls, keep an eye out for this.
