Currently, it is possible to supply an invalid combination of a physical and logical type to rdf to-jelly command, like:

jelly-cli rdf to-jelly ./in.nq --to ./out_invalid.jelly --opt.logical-type=SUBJECT_GRAPHS --opt.physical-type=QUADS

The file is produced with no issues and the error appears only when validating/inspecting/deserializing the file.

It would be nice to show a warning/error during serialization, so as to prevent users from creating invalid jelly files.
