This is a companion PR to geoschem/geos-chem#3050. It updates the area export in offline advection from REAL4 to REAL8. This export is received as an import in GEOS-Chem where it is stored in the State_Grid object as double precision floating point. Since it is computed as REAL8 in FV3 we should be exporting it as REAL8 not REAL4.

This PR fixes geoschem/GCHP#514 when merged with the companion GEOS-Chem PR.
