Merge branch 'xylar/mesh/add-icoswisc30e3r5' into next (PR #6079)
Browse files Browse the repository at this point in the history 
Add new IcoswISC30E3r5 ocean and sea-ice mesh

This nearly uniform 30 km mesh is the dual mesh of a subdivided
icosahedron (Icos). The mesh is with Ice-Shelf Cavities (wISC) around
Antarctica and has 64 vertical layers. This version of the mesh does not
include smoothing of topography.

This mesh is a candidate for the E3SM v3 (E3) low res mesh. It is
revision 5 (r5) of the mesh.
