* Support importing features from RDF whose times are intervals rather
than only instants; import them into region or note models. Sadly
this makes RDF import much, much slower, because we need to work around
Rasqal's single-OPTIONAL limitation by repeatedly querying each feature
for time and range.
* Add segmentation view to region layer, and display label texts
