It would be nice to have the information if a strip triggered / was a nearest neighbor, and if the timing type was 1 (fast) or 0 (slow).
I think #183 is proposing to write nearest-neighbor strip hits as NN instead of SH, but the problem with loosing information if the TAC value is based on fast or slow timing (HasFastTiming) still remains.
