Hotfix for offline domain check longitude range

[SamuelDegelia-NOAA]

A quick fix for the problem described here by @HuiLiu-NOAA. The conventional version of the offline domain check was not configured to work with obs whose longitudes range from (-180, 180). This line exists in offline_domain_check_satrad.py but needs to be added to offline_domain_check.py.

LGTM! This is an easy one. Thanks for making the PR for this.

Thanks! I think this offline tool would remain very useful even after the online one is fully functional.

I agree with this statement. Just the other day, it came up about matching ob counts when we do FV3 vs MPAS comparisons since grids wont match 100%. We can use the smaller of the two grids using the offline domain check to get the exact number of obs when doing our comparisons.
