adding macro to create space charge density maps from simulations

For each created space charge density map the IDCs (3D, 1D, 0D) and the
distortions/corrections are calculated and stored in root files.
This macro can for example be used to create the input data for the ML algorithms
which will be used to correct the space charge distortions.
The input to create the density maps are hits from an O2 simulation ("o2sim_HitsTPC.root").
