ITk seeding for TrigFastTrackFinder
Contains the implementation of new seeding algorithm for ITk by @demelian. Also contains new standalone python file in TrigFastTrackFinder called "ITkFastTrackFinderOffline.py" which allows TrigFastTrackFinder to run as an offline algorithm when added as a postInclude option to Reco_tf.py. For example:
Reco_tf.py --maxEvents=100 --inputRDOFile RDO.29843243.ttbar200PU.pool.root.1 --outputAODFile AOD.root --CA --steering doRAWtoALL --preInclude InDetConfig.ConfigurationHelpers.OnlyTrackingPreInclude --postInclude TrigFastTrackFinder.ITkFastTrackFinderStandaloneConfig.ITkFastTrackFinderStandaloneCfg > output.log 2>&1 &
This does not change the normal operation of TrigFastTrackFinder as the new seeding is off by default. This is part of EFTRACK-7, EFTRACK-4 and EFTRACK-142
