Muon background no m1 fix
Few fixes for no M1 simulation. Using the code without this fixes
- M2 low energy was not added
- in M3 M4 M5 the wrong parametherizations were uses (M3 uses M2, M4 uses M3 and M5 uses M4)
- in flat background addition wrong number of hits were added Please not that the code on this branch does not allow the simulation with M1 anymore.
