Improve vertical transformation support
When we had a transformation between a compoundCRS and a target geographicCRS,
we did not take into account that in the vertical->other_geog_CRS transformation
we used, the other_geog_CRS was an implicit interpolation CRS. Thus before
doing vertical adjustment, we must go to this interpolation CRS.
The workflow is thus:
source CRS -> interpolation CRS + vertical adjustment + interplation CRS -> target CRS
