Recent changes to how FGCM and jointcal calibrations are persisted break the way we apply external calibrations in `faro`. Update the relevant code in `faro` to enable external calibration.

The specific error that happens when trying to run `faro` on the w_2021_14 processing of RC2 data is "Quantum graph is empty."

From J. Bosch in #dm-science-pipelines on Apr. 20: "I bet some of your current input dataset types have changed form in the Gen3 versions of the tasks that produced them.  One big candidate is that FGCM and jointcal now write their outputs to per-visit catalogs (one row for each detector) with different dataset types, so if you'd been using those to calibrate your single-visit catalogs, and those were regular input connections, an empty QG is what you'd see."
