Describe the update
This PR disables pole-averaging in the map_a2a horizontal regridding scheme when using CESM. This avoids introducing differences in 2D emissions when using different numbers of cores. This PR also updates several print statements to limit to root thread in order to reduce log redundancy when using MPI.
Note that after this PR there is still an issue in CESM with core-dependency. However, it will be limited to 3D emissions only.
Expected changes
This will be a zero difference update for GC-Classic and GCHP.
