Publish elevator component poses for visualizing robot movement in simulation & match recordings

Each elevator stage must be its own component, so they can be animated independently. Their positions can simply be a function of the current elevator height and assume the stages move in a predictable sequence.
This would help visualizing robot behavior from match recordings, where the elevator is currently shown as static in the 3D model.

Unfortunately, the assumption that the stages move in a predictable sequence is not always true, but it'd be better than nothing.
