When neutral mesoscale eddy-induced diffusion is enabled with namelist option ltedtp = "neutral", this PR adds functionality so that interfaces of layers constructed for diffusive flux computations may be gradually aligned with the surface within the mixed layer. This functionality is enabled by setting a new namelist variable ndiff_surface_align = .true.. The default setting of ndiff_surface_align = .false. gives bit-identical results with current master.

…ed for diffusive flux computations with the surface within the mixed layer.

The aux_blom_noresm tests PASS, with expected name list fail (NLFAIL) when comparing with noresm3_0_beta12a.
