MuCh geometry lmvm v23a

Apar Agarwal requested to merge a.agarwal_AT_vecc.gov.in/cbmroot_geometry:master into master

------------------------- Updates in the Geometry, Tag v23a ------------------------------------

  1. Correct Readout Shape has been implemented and dimensions now match the actual readout pads for Station 1 and 2 Segment sector file creation method has been merged in the geometry itself-- now we don't need dedicated codes or roundabout methods to create these files
  2. Approximate likeliness of edge frame has been implemented with FR4 material
  3. FR4 is also used for Readout and Drift
  4. PCBs for FEE Boards and CNC holes in the Aluminium support have been implemented
  5. C Plate for the support (Station 0 with clamp and Station 1 without clamp) has been implemented
  6. Metallic supports have been implemented in Station 1 and 2 with material set to steel
  7. Readout and Drift region on PCB has Copper (65 micron) + Nickel(5 micron) implemented as per info provided by the manufacturer
  8. Active Region, Passive volume , Drift region (on PCB), Readout region (on PCB) and Foil Components are now sector shaped instead of trapezoidal

In summary, the geometry for first and second station is now made almost according to latest engineering drawing. The Geometry for Third and Fourth station is still under planning hence the changes are limited to the number of stations and segmentation scheme only.
