Corrects STS v21e position error

Transformation between local sts origin (last station) and global origin (center of magnet) is now 59.5. Front face of sts to intended position of target (-44cm) is now 1.6 cm.

 Summary:
   This version adds passive materials imported from GDML model to the STS geometry:
     * Taken from and largely correspond to mechanical CAD drawings of the detector
