Convert TtracksCatboostFilter to use Pr::Seeding::Tracks instead of v1 tracks, fix T track calorimeter reconstruction
Ttracks MVA filtering: Following on from !3646 (merged) and Moore!2731 (merged), the decloned PrSeeding tracks can be used in the MVA filter, then the output can be Kalman filtered. Goes with Moore#657. Currently did a minimal conversion of the code, but sections can probably be vectorised (except the evaluation of BDT).
T track calorimeter reconstruction:
Adds TrackAncestorAssociator algorithms to associate a provided set of tracks either using the object key or by the fromIndex
in a RelationTable1D
Changes the PrKalmanFilter
to insert v1 tracks with a key corresponding to the index in the Pr container
This is required as the unfitted T tracks are used in calorimeter reconstruction, but (possibly filtered) fitted T tracks are used in selections
Configured in Moore!2784
Depends on LHCb!4361 (merged) and LHCb!4385
