This package derives zero/wilt/reference/saturation anchors from the STAS
MAXSMC, BB, SATDK and SATPSI constants, using set_soilveg's SMHIGH=6 and
SMLOW=0.5 expressions. Its urban blend follows sflx. This is a modified
representation of the source parameters, not an official NOAA product.
The corresponding target constants are from the pinned MPAS Noah STAS table;
see hexcore/cycle/NOAH-TABLE-NOTICE.txt for its public-domain source.
