Describe the update

As discussed in #2513, EDGAR v8.0 livestock emissions have been found to have unexplained hotspots. They also lack seasonality. To address these issues, we revert to EDGAR v7 emissions for that sector and apply seasonality from EDGAR v6 as we did in previous GEOS-Chem versions.

Expected changes

This is a zero difference update w/r/t full-chemistry benchmark simulations. For CH4/carbon simulations it will impact the annual anthropogenic emissions.
