Offset to add to the index of each sim hit to account for which crossing it's in.

I need to know what each sim hit index will be when the hits from all crossing frames are merged into one collection (assuming the MixingModule is configured to create the crossing frame for all sim hits). To do this I'll record how many hits were in each crossing, and then add that on to the index for a given hit in a given crossing. This assumes that the crossings are processed in the same order here as they are put into the crossing frame, which I'm pretty sure is true.
The key is the name of the sim hit collection.
