Raise error when no gridded data is loaded #212

scotthavens commented 3 years ago

When loading a gridded dataset whose domain does not match the topo.nc domain, it will show that 0 cells within model domain but SMRF will continue on and try to interpolate. Suggest raising an error to alert users that their input data doesn't match the model domain.
