Seeding & matching momentum parametrization fix
MR to fix Seeding&Matching mass bias first observed in 2022 data-taking. The mass bias has also been identified in simulation and was traced back to the qop parametrization.
In the old version of the code, the qop parametrization is adapted from FastMomentumEstimate.cpp . In this update we switch to the parametrization from SciFiTrackForwarding.cpp . Mass distributions from selected events of the KsToPiPi and Dd2KPi Hlt1 lines now seem compatible between the forward and matching sequences (using minbias and Dst2D0 simulation samples respectively).
