Add more arguments to publish_as_nanopub method
The `Nanopub.from_assertion` method that the `publish_as_nanopub` method is based on accepts arguments `attributed_to`, `attribute_to_profile`, and `nanopub_author`. We should allow the user to pass those arguments also to `publish_as_nanopub` so when publishing a workflow or step users can control the author of the nanopub and the assertion.
