Pixel Error Athena Monitoring in the new AM framework
PixelAthErrorMonAlg is essentially implementation of PixelMonitoring/src/Errors.cxx code of rel. 21.0 in the new monitoring framework. It requires input from PixelByteStreamErrorsTool, which is currently not provided (as the tool is being migrated), so PixelAthErrorMonAlg is now producing profile error histograms filled with zeros. It has been tested with some dummy input, though will require proper validation wrt rel. 21.0 once the input data is provided.
