Magnet redesign

Magnets have a wider apperature by 300mm, and a
higher opening by 30mm to allow for a redesigned
STS detector.

+magnet_v22a.geo.root is made from magnet_v22a.gdml, available from the gdml repo using the following commands
+
+root -l << EOT
+TGeoManager::Import("magnet_v22a.gdml")
+TFile newfile("magnet_v22a.geo.root","recreate")
+TGeoVolume* gdml_vol = gGeoManager->GetTopVolume()
+newfile.WriteTObject(gdml_vol)
+newfile.Close()
+EOT
+
+compared to v21a, the magnet has a renamed top volume to better follow convention.
+It enlarges the width of the apperature and entire gometry by 30cm in the x direction.
+It enlarges the height of the apperature and entire yoke by 3cm in the y direction (height).
+The clamps are elongated in x but the positioning is maintained.
+
+Default geometry to be used as the clamps are to be used with and without the rich detector.
+The only acception when the MUCH is used when the other magent geometry is to be used.
