LArLATOMEBuilderAlg: Property use data-pool
The LArLATOMEBuilderAlg does use a DataPool (designed to avoid unnecessary re-allocation of small data objects) but they way it is used leads still to frequent (re-allocation) of small data objects.
This MR adds the necessary setters to LArRawSC to overwrite all members of recycled data objects and uses them to really avoid frequent,small memory-allocations.
