jena-arq does not need to export `org.apache.jena.atlas` - it needs to
export `org.apache.jena.atlas.csv`, org.apache.jena.atlas.data` etc.
`org.apache.jena.atlas` does not depend on `riot`, it only has two classes,
both exceptions.
This is the case for `org.apache.jena` in "jena-core". `org.apache.jena`
subpackages are everywhere.---
