anaDACScan.py update: handle the case when the OH number is not in the chamber dictionary

Handles the case when an OH in the input tree is not in the chamber dictionary.

Description

This pull request introduces a dict_chamberNames and sets the chamber name to unknown for OH numbers that are not in the chamber_config dictionary.

Types of changes

[x] Bug fix (non-breaking change which fixes an issue)
[ ] New feature (non-breaking change which adds functionality)
[ ] Breaking change (fix or feature that would cause existing functionality to change)

Motivation and Context

This pull request resolves https://github.com/cms-gem-daq-project/gem-plotting-tools/issues/173

How Has This Been Tested?

I have tested the script (in a venv) for 3 cases:

1) OH in chamber config

Initializing TObjects
Looping over stored events in dacScanTree
fitting DAC vs. ADC distributions
Determining nominal values for bias voltage and/or current settings
Warning: when fitting DAC CFG_BIAS_PRE_I_BIT the fitted value, 274, is outside range the register can hold: [0,255]. It will be replaced by 255.

2) OH not in chamber config and no calFile is passed

Warning: OH0 not found in chamber name dictionary. The chamber name associated with this OH will be set to 'unknown'.
Skipping OH0, no calibration file
No OHs with a calFile, exiting.

3) OH not in chamber config and calFile is passed

Warning: OH0 not found in chamber name dictionary. The chamber name associated with this OH will be set to 'unknown'.
