Shea occlusion manager

This PR compromises the version 1 of the occlusion manager, focusing on masking the SimulationHistoryBuffer input to the ego planner based on some rule.

It also contains a number of misc changes to support visualizing occlusions. I think checking out test_notebook.ipynb is the best way of intuiting how to run things. Let me know if there are any questions.

Looks very good. I'll merge this into dev as soon as you address the comments.
