SIM&REC: import stitching vertex

• Geometry
  • SiTrackerStitching_v01 construct for stitching vertex, through option Detector/DetCRD/compact/CRD_common_v02/VXD_Stitching_v01_01.xml
  • SiTrackerComposite_v01 construct for composite of stitching and planar, through option Detector/DetCRD/compact/CRD_common_v02/VXD_Composite_v01_01.xml
• Digitization
  • CylinderDigiAlg for digitization: simple smear now
  • SmearDigiTool for both planar and cylinder, using DD4hep surface
  • SiTrackerDigiAlg optional to use different digi tool through IDigiTool interface
• GearSvc
  • convertStitching(dd4hep::DetElement&) to convert dd4hep::rec::CylindricalData extension data to Gear
  • convertConposite(dd4hep::DetElement&) to convert dd4hep::rec::CompositeData extension data to Gear
• CEPCVTXKalDetector support both planar and cylindrical
