AST-970 Extend FacetImage to store and allow retrieval of facet.
There is already as SetFacet()
method in FacetImage
. This method updates the geometry, but it does not store the Facet
.
For the dd-psf work in WSClean it is convenient to be able to retrieve the Facet
object from a FacetImage
later on.
This MR adds a facet_
member that is set by the SetFacet() method and can be retrieved by the GetFacet() method.
