Managing detector information

[siilieva]

Need to have a strategy for book keeping of the detector details.
Example: SND@LHC uses the geometry config file for storage of all details of the geometry : positions, dimensions, calibration.
Currently for AdvSND we have the geo config with most of the geo parameters and also a header SiSensor.h with more details on the arrangement of the detector elements.
It is reported there is duplication of data already, while this is to be AVOIDED.

To add some more context, ideally most constants should be moved somewhere accessible by python (gInterpreter.ProcessLine('#include "SiSensor.h") can be a workaround but is not a nice solution), while hopefully some of the code duplication between the two detector classes can be moved to the SiSensor.h header.

A classical solution alla Thomas will be to add the SiSensor as a ROOT dictionary and import ROOT in py code, which we are already doing almost all the time
