Add ObsError group to radiance IODA obs via the offline domain check

[SamuelDegelia-NOAA]

Bug Fix Description

This PR addresses #274. To prevent the empty DerivedObsError group from being created and used during LETKF, we need to include ObsError in the input IODA data for radiance obs. The bufr2ioda converters for radiance data are still in active development and are not ready to be committed to RDASApp. Thus, the easiest solution for us is to add ObsError via the offline domain check.

Here I updated offline_domain_check_satrad.py to create a ObsError group. The errors are initialized at 999 but will be filled in by the assign error filter action once JEDI is run. New radiance obs are created using this code and staged in RDAS_DATA. Those new obs are linked into RDASApp under this PR which resolves the issue of zero increments when running LETKF for these ob types.

The addition of the ObsError group to the IODA data only affects the LETKF solver. The ctest references for the Ens3Dvar are the exact same as before.
