Bug fix for pixel charge calibration (ATLASRECTS-7155)
Apply the linear extrapolation for very large charge that does not go to FPE nor negative. Also add protection for very small charge which does not go below threshold.
They are activated when
PixelConfigCondAlg.doRUN3PIXLinearExtrapolation=True
Current default is False. So that, this should not change any results.
Once this change is approved by physics groups, we would activate this flag as True.
