NEON release: Some NEON updates fixing AG sites, update MOSART, small fixes

release tag for use with NEON:

Minor changes to python scripts and usermod_dirs for NEON cases. Also update the lightning mesh file so that it goes with the
smaller lightning file. Have NEON use new use-cases for 2018 and 2018-PD conditions for CLM. Have NEON
Agricultural sites run with prognostic crop. Simple fix for warning about NaN's in import/export data from/to coupler.

Get NEON tests working on izumi, add --inputdata-dir to subset_data and modify_singlept_site_neon.py so they aren't tied
to only running on cheyenne.

Also update MOSART with fixed for direct_to_outlet option.

Add error checking in ParitionWoodFluxes. Fix value of albgrd_col in SurfaceAlbefdoType.F90.
Previously, the wrong value (albgri_col) was being set in InitHistory.
