Move Falcon integration from SuperXAS to Ophyd_devices
Summary
The Falcon integration with MCARecords, and adaptions to allow readout of ROIS as it was done at SuperXAS (https://gitlab.psi.ch/bec/superxas_bec/-/blob/feat/add_devices/superxas_bec/devices/falcon.py?ref_type=heads) should be moved to ophyd_devices.
Additional notes
Note, we were not able to load the integrated ophyd device of the Falcon at the beamline when the IOC was not running. We should investigate whether this is linked to manually setting the _default_read_attributes (https://gitlab.psi.ch/bec/superxas_bec/-/blob/feat/add_devices/superxas_bec/devices/falcon.py?ref_type=heads#L95).
