Allow NSW lookup tables to have duplicated detector elements for the split robs
In the NSW apparently eacvhj detector element will be read out by (up to) 4 ROBS and as such multiple ROBIDs are required for the detector elements.
As a quick hack the detector elements are added multiple times, once for each ROBID, so this change should removed the duplicate hash IDs from the output list for the MM And sTGC instances. See for instance pscholer/athena!2 (closed) which could in principle be merged before, or after this MR.
A more complete fix might be required in the near future.
