CO2 rotation Stage Calibration

After we found the CO2X power has been degrading in 72943, I recalibrated the CO2 rotation stages this morning. Last done in March 66724.

Added a README.txt file to /opt/rtcds/userapps/release/tcs/h1/scripts/RS_calibration/ with instructions.

Also adjusted lscparams to output the existing values. Plan to relock with yesterdays output and then during lock, adjust CO2X to output 1.68W as the start of O4.
