Saving timing for all supercells

The timing cut is currently computed only for supercells with E > 50 MeV: https://gitlab.cern.ch/atlas/athena/-/blob/21.3/LArCalorimeter/LArROD/src/LArRawChannelBuilderToolOFC.cxx#L41

The default can be changed for supercells in the supercell getter. It turns out – that makes a HUGE difference in the performance when you cut on the time, as there is a significant bias toward negative ET supercells. Using gTowers as an example:

avg gTower ET: all supercells have timing = 140 MeV
avg gTower ET: only supercells with E > 50 GeV have timing = -720 MeV
