WIP: core: exporters: graphol_iri: export all IRIs known to the project

This includes datatypes, facets, and top/bottom IRIs since we want to
support non-graphical IRI.
Note that due to this, when selecting a subset of the diagrams you stll
get the IRIs of those, as there is no way to distinguish between them.
