23.0-reduce_CC-PixelCalibAlgs

This does not affect any normal workflow; the code concerned is for doing pixel calibration only. Addressing ATLASRECTS-7562, this reduces the length of the calibration macro code from 4017 lines to 1003, and the maximum cyclomatic complexity is reduced from 461 to 54 (still not fantastic, but a lot better). The output.dat file has been compared with the original (rel 22) code and found to be identical.
