Ecal clustering sanity checks
Add sanity checks following the validation of new Sim10-Up08 simulation:
- remove clusters with negative energy at the end of CellularAutomaton and ShowerOverlap, adding respective counters
- align the check for negative energy clusters in the Spread tool to the above
- add counters to Spread tool, change
StatEntity
counters to `Gaudi::Accumulator`` - add debug info in PhotonMatch
- fix typo in energy counter in ShowerOverlap
Due to the addition and changes of the counters, differences are expected in the references.
