The remapper does not work for purely vertical spaces

[Sbozzolo]

Remapping.Remapper assumes that there is an horizontal space, so it cannot be use to interpolate purely vertiacal fields. It would be nice to lift this restriction so that ClimaDiagnostics can be used directly on vertical spaces.

What would remapping on a purely vertical field mean? Isn't remapping a horizontal operation?

Our remapper performs linear interpolation on the vertical direction, so it would just do that
