> This comparator creates bounding boxes to avoid calling haversin(), so its no
> longer a hotspot for most use cases.
> But in the worst case, it could still get called many times. This could be
> because the user had a massive top N value, or because the incoming data is
> sorted or mostly sorted by decreasing distance, etc.
> We can optimize the worst case by not invoking a full haversin, just using
> something that is rank-equivalent.
