rdf to-jelly: add PHYSICAL_STREAM_TYPE_GRAPHS support #101
Description
Currently, there is no way to enforce PHYSICAL_STREAM_TYPE_GRAPHS with stream options via jelly-cli.
As the specification has certain requirements for this physical type, e.g. here:
A graph corresponding to one graph node MAY occur multiple times in a stream or a stream frame. The consumer MUST treat all occurrences of the graph as a single RDF graph.
A graph MAY span more than one stream frame. The consumer MUST treat the graph spanning several stream frames as a single RDF graph.
This behaviour is expected to be covered by the conformance tests and requires the respective functionality.
