New topo-cluster moment & data size reduction for forward topo-towers
New topo-cluster moment:
- implemented the second moment of the cell time distribution in a topo-cluster for additional signal characterization;
- moment SECOND_TIME is added to xAOD output item list for the CaloCalTopoClusters container;
Disc space reduction for the CaloCalFwdTopoTowers container:
- the vector of sampling energies is cleared for each forward topo-tower;
- additional non-trivial data members like the nominal tower bin center are set to 0;
- the number of reconstructed moments attached to each forward tower is reduced to three (LONGITUDINAL, ENG_FRAC_EM, SIGNIFICANCE) plus two moments indicating bad cell contributions;
