The ESMF weights used to remap the tripole ocean and ice output to rectilinear grids requires a fix to properly remap the tripole seam region.

The weights currently residing in the fix directory /scratch1/NCEPDEV/climate/climpara/S2S/FIX/fix_UFSp6/fix_reg2grb2 were originally generated many years ago (perhaps on Theia) and have been used for the Prototype post-processing. Those weights should be replaced with the new weights generated with the fix.

Note the existing weights do have the proper -90:90 bounds. However, the cpld_gridgen run script did not include the proper setting to generate the -90:90 bounds when executing the ncremap command.

The weights are not retained within the UFS_UTILS baseline directories and so no baseline change for UFS_UTILS is expected.

cpld_gridgen: Fix weights generation for tripole->rectilinear output …
41f7ca9 
…of ocean and ice (#858)

When generating rectilinear destination grids, set lat_typ=cap in order to obtain a grid from 90S to 90N. 

Also, return an optional RouteHandle (un-used) when generating the ESMF Weights. This creates a weights file which properly generates values along the tripole seam.
