Update FPA position of all visible cameras after cooling down in October 2024

New FPA position was measured after pump/cool down in October 2024, except for SM1.  Update xcu.yaml accordingly: 

• xcu_b2 motors moveCcd a=218.59 b=226.29 c=220.52 microns abs
• xcu_b3 motors moveCcd a=179.89 b=161.48 c=181.74 microns abs
• xcu_b4 motors moveCcd a=115.38 b=74.94 c=130.55 microns abs
• xcu_r2 motors moveCcd a=162.86 b=187.66 c=164.34 microns abs
• xcu_r3 motors moveCcd a=191.01 b=179.70 c=179.29 microns abs
• xcu_r4 motors moveCcd a=98.45 b=47.82 c=93.39 microns abs

Note that most of camera position was changed by ~20um, because camera temperature is lower by ~3K now.
