Draft: add muon resolution category variable to PHYSLITE

This variable is used in the columnar version of the MuonCalibTool to avoid the need for that tool to hold a MuonSelectionTool internally. Besides simplicity this also greatly reduces the number of input columns needed.

This adds a single integer to each muon in PHYSLITE, from a limited set of possible values. This is 5 bytes/event in my tests. I would have expected something closer to 1 byte/event based on the amount of information that needs to be stored, but that is probably more an issue for another day.
