[BUG/ISSUE] AODs for several species are mixed up in GEOS-Chem 12.8.0

[msulprizio]

In the GEOS-Chem 12.8.0 benchmarks, it can be seen that the AODs for several species are mixed up. This appears to be a diagnostic issue in the GEOS-Chem output.

This is now fixed in commit aade347 and will be included in 12.8.1.

The issue was in the use of the State_Chm%Map_HygGrth and MAP_NRHAER arrays in subroutine RDAER (found in GeosCore/aerosol_mod.F90). The ordering of species in those two arrays was the same in 12.7.0 and earlier (1=SO4, 2=BC, 3=OC, 4=SALA, 5=SALC), but the reordering of species in input.geos to alphabetical order changed the order in State_Diag%Map_HygGrth in 12.8.0.

A difference test with the previous commit shows differences only in the Aerosols collection, confirming that this was an issue impacting the diagnostics only.
