Add in-pixel efficiency taken from a reference map obtained at test beams. The map is currently available at
/alice/cern.ch/user/g/glucia/ALICE3/IOTOF/pixelEfficiency/PixelEfficiencyMap_TH2.root
The residual distribution of the digit-to-hit position is used as a proxy of the efficiency to display the effect. Uniform distribution when the efficiency is flat
(x-axis: residual in z [cm], y-axis: residual in x [cm]) --> the distribution of digits is flat
(x-axis: residual in z [cm], y-axis: residual in x [cm]) --> the distribution of digits is less populated at the edges, where the loss in efficiency is introduced
