New R3BFootCal2Hit for FOOT detectors

[AndreaLagni]

New r3BFootCal2Hit task. From the point of view of the clustering and position reconstruction the task did not change. The most important modification is the eta-energy calibration. The task include both calibration for S522 and S509. It possible to use one or the other with SetExpId(). This task allow to obtain a better separation of the charges in the FOOT detectors, in particular, if we look at the at the correlations between the 2 FOOT inside the vacuum chamber (charge 3, 4, 5, 6) for C beam (S522). Still charge 1 and 2 are not well defined since they are covered with noise that set a very low value of energy. This pull also include the possibility to have the eta parameter at the hit level and small modifications of the R3BFootMapped2StripCal.
