tauRecTools: add tau track flag to identify LRTs more easily

Bertrand Martin Dit Latour requested to merge martindl/athena:R22_IgnoreLRT into master

Hello,

This MR is adding a tau track flag to identify large radius tracks more easily, when LRTs are enabled in the tau reconstruction. We can now retrieve specifically the LRTs associated with the tau via tau->tracks(xAOD::TauJetParameters::TauTrackFlag::LargeRadiusTrack). This flag is agnostic w.r.t. the track classification, it is only used to tag LRTs, which will be useful e.g. to count LRTs within 0.4 of the tau axis.

The number of LRTs associated with the tau is added as a new Aux variable.

A problem was also found in the calculation of the nAllTracks Aux variable recently introduced. The computation was made too early, after the "core" and "isolation" tracks are associated with the tau, but before the "other" tracks are associated. This has no consequence though, as this is variable is not directly used in the reconstruction.

Cheers, Bertrand
