Adding python module file in order to call the Pixel Calibration

This MR is meant to add the python module in order to call the calibration of Pixel.

It allows to set up Athena, and run the command as (it is a working example):

python -m PixelCalibAlgs.PixelCalibrationConfig --folder /eos/atlas/atlascerngroupdisk/det-ibl/charge-calibration/20230525_BLAYER/ --thr SCAN_S000089590 --thr_intime SCAN_S000089593 --tot SCAN_S000089594 --layer Blayer L1

The capability of this python file will be to run the full calibration chain with just one command line (still in progress).

We can also run all the pixel layers in parallel adding to the argument the rest of them like --layer Blayer L1 L2 disk
