Added the "isosub" to the cifinput and cifoutput sections, mapping
it to the "substrate cut" (GDS 81:53) layer.  This allows substrate
regions to extract independently.  Note:  Currently this may require
copying the "isosub" layer up through the entire hierarchy to the
top level for the extraction to work correctly, pending a commit of
ongoing work to enhance the substrate extraction method in magic.
