[AGIPD] Read bias_voltage for AGIPD at SPB and MID from RUN source

get_bias_voltage() read bias_voltage for HED_DET_AGIPD500K2G only.

Description

Start using SPB_DET_AGIPD1M/PSC/HV/channels.U0.measurementSenseVoltage.value and MID_DET_AGIPD1M/PSC/HV/channels.U0.measurementSenseVoltage.value to ready bias voltage for SPB_DET_AGIPD1M-1 and MID_DET_AGIPD1M-1.

How Has This Been Tested?

Types of changes

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

Checklist:

• I have updated the documentation accordingly.
• I added tests where appropriate. A part of a different MR: https://git.xfel.eu/detectors/pycalibration/-/merge_requests/646
