Describe the update

This PR contains fixes for the GCHP carbon simulation introduced in version 14, not to be confused with the CO2 w/ fluxes simulation option used for the adjoint.

There is a companion MAPL PR that should be merged at the same time as this PR to include all GCHP carbon bug fixes.
geoschem/MAPL#37

Expected changes

This is a no diff update for GC-Classic. Changes only impact the carbon simulation in GCHP.

The data in molec/cm2/s is converted to kg/m2/s automatically if reading
data in through HEMCO. Since GCHP does not use HEMCO for data read we
need to instead specify a scaling factor in a configuration file. This
update fixes a bug in GCHP carbon simulations where CH4 emissions were
applied in the wrong units.

This commit also fixes a bug where several ExtData.rc entries for
gridded GHGI v2 Express Extension emissions were specified as monthly
when they are actually annual.
