udpated stave material budget for the baseline design.
see https://eicweb.phy.anl.gov/EIC/detectors/athena/-/issues/63
ITS3 sensor thickness: 40um, pixel size: 10um (segmentation)
total X0 0.55% per layer:
0.4 mm aluminum ~ 0.44% X0.
2 x carbonfiber (RL ~ 25) 0.1 mm to match Si (RL~9) of 0.04mm

Layer_rOffset is used to add inside space so the _rmin value is the nominal sensor radius. Layer_rOffset is used to add inside space so the _rmin value is the nominal sensor radius.
TrackerBarrelSpaceFrame_height must be smaller than {_rmin2 - _rmin1 - Layer_rOffset - 1mm - stave_thickness}
