LArRawChannelBuilderAlg: Add option to use compute Q and t only for positive-energy cells
During run1/2 the MC-reco (actually digitization) computed LArRawChannel Quality and Time only for cells with E>Ecut while for data |E|>Ecut was used. The current run-3 implementation uses |E|>Ecut for all cases.
This MR introduces a new property that allows to switch back to the E>Ecut behavior (eg do not compute Q and t for negative-energy cells). This might be useful for the Trigger-simulation.
