[AGIPD][FF][PC] Fixes for AGIPD HZ gain constants

Description

This MR provides collection of fixes needed to enable processing of gain constants for AGIPD HZ modules.

FF Histogramming

• Introducing roi for analysis of data quality as it cannot been done for whole module due to only few installed ASICs.
• Changed pixel used for control plot, again due to not all basics being present in the setup.

FF

• Introduce possibility to plot data in log scale and change pixel used for control plots.

FF Summary

• Exposing all fit parameters to allow applying the current processing values to fit histogram for control plot.
• Disabling QM notation for single modules.
• Changing plot size for better resolution.
• For performance plot load AGIPD data of the processed instance. This is needed as HZ modules are treated as separate detectors.

PC

• Added BP mask to properly sanitise constants.
• Changed pixel ranges (due to missing AISCs)
• Disable gain stage assignment for HZ modules based on dark thresholds.
• Disabling QM notation for single modules

How Has This Been Tested?

Tested with the FF and PC data in p900478 and for compatibility with other AGIPDs with data in p900508.

Relevant Documents (optional)

Types of changes

• Bug fix (non-breaking change which fixes an issue)
