In this case, you cannot use a scorer. A scorer by definition
sums one physical quantity for an event. You should create
your own sensitive detector to record each photon. Note that
you can still use G4SDParticleWithEnergyFilter to be attached
to your detector, thus your detector should simply record each
step.
