This PR changes the default earth_radius_km value for the hex_projection tool to 6371.229 km.

MPAS-Atmosphere uses a sphere radius of 6371229.0 m, and since the hex_projection tool is intended primarily for use with MPAS-Atmosphere, this PR sets the default sphere radius provided in the namelist.projections file for the hex_projection tool to match that value.
