Update of Alignment for 2024 data

Wouter Hulsbergen requested to merge wh_update_alignconstraints into master
  • fix bug in AlDoFMask affecting the printout of the lagrange constraints
  • improve the naming of constraints: the shearings are now called SzTx rather than Szx. SzTx means a Tx linear in z.
  • added constraints SxRz (rotation as function of x), SxTz (Tz as function of x) and Sx2Tz (Tz as function of x^2)
  • fix bug in track ordering for selecting tracks for PV division
  • rationalize use of PV filter for FT alignments
  • make sure all relevant velo tracks are present when using PVs as input to tracker alignment
  • update D0 particle selection (tighten IPCHI2 cut for input tracks; add DLS cut for mother)
  • add J/psi and Z0 particles to alignment
  • add Upsilon selection for monitoring
  • add AlignVertexTrackExtracter which can be used to add only tracks in selected PVs to alignment
  • add lagrange constraint relative to survey
  • add information on residuals for joint constrains per alignable
  • add option to specify a pivot translation for the alignment frame (to be used for FT half modules)
  • fix #116 (closed)
  • improve performance when running in multithreading mode
  • add scenarios and test for global alignment (VP/UT/FT)
  • revive histogramming functionality of AlignAlgorithm
  • clean up SurveyConstraints; add default survey files for nominal VP geometry
  • fix bug in retrieving motion system transform in detdesc
  • fix bug in some validators testing for convergence

this needs Rec!3882 (merged)
