To be checked with experts if details needed, here is extrapolated from diff to v21h/v21i
- Shift front forward by 14 cm
- Shift front stand toward negative X by 50 cm (compensated in other place)
- Double readout strips in SM Type 4 (diamond/BMon) from 8 to 16
- Shift modules start position in SM type 2 by 6 cm toward positive X
- Increase distance in X between modules in SM type 0 and 2 by 0.7 cm
- Fine-tuning of each SM position, includes compensation for X shift of front position\
  => At leats shift of +1.5 cm in Y of each, but also more changes for some types

- Include fix for radiation length error, should be base of further mCBM geometries!!!
