Detector Parameters Update: PFRICH about epic

[Chao1009]

Hi @kkauder, do you have a plan for updating the parameters?

[kkauder]

@Chao1009 Could you tell me what test to run after I make changes and see a new report?

[kkauder]

Also, what's the preferred procedure? Should I hardcode values in https://github.com/eic/epic/blob/main/compact/definitions.xml? Or still use something like the existing

    <constant name="BackwardPIDRegion_zmin"       value="CentralTrackingRegionN_zmax" />

and rely on CentralTrackingRegionN_zmax (eventually) being correct?

@Chao1009 please check that #595 does what is needed. Two notes:

• pfRICH calls the "less negative" value z_min, so you need to swap that in the tester
• The bore is asymmetric (not in this simple version but in reality), about 8 cm in the short direction, 10 in the wide direction. I chose the a circle with the bigger radius to avoid any beam pipe overlap problems.
