Feature request: Add a parameter that enables merging multiple instances of the same axiom with different sets of axiom annotations

Derived from #1098

When terms are defined in two different inputs, the act of merging may lead to duplicate annotations. It would be nice to have a quick way of removing such duplicates when is clear that the annotation is indeed the same.

[jamesaoverton]

Sorry, I don't understand. It would be good to have some concrete examples.

1. An OWL annotation such as OBI:0000070 rdfs:label "assay". is an RDF triple where the predicate is an OWL Annotation Property. You should never see duplicates of these -- OWLAPI or any RDF library will merge them.
2. An OWL axiom annotation using reification <OBI:0000070 rdfs:label "assay"> rdfs:comment "Comment". This is trickier, but I would not expect to see duplicates of these either.
3. From the context of #1098, the problem seems to be "duplicates" from --annotate-derived-from or --annotate-defined-by, but are they really duplicates or just more information than you want?

It would be somehow better if we could do instead with a nice parameter output:

[jamesaoverton]

Is this just an artifact of the Manchester syntax renderer? Does it also happen in RDF/XML format?

[matentzn]

I think this is part of the owl api object model, I.E will be reflected by all renderes. I know it does for OBO, OFN and RDF XML.

[jamesaoverton]

Does robot repair --merge-annotation-axioms true address this issue?

It's currently undocumented, so I didn't realize it was in the code already: https://github.com/ontodev/robot/blob/master/robot-core/src/main/java/org/obolibrary/robot/RepairOperation.java#L123

[matentzn]

robot merge -i test.owl repair --merge-axiom-annotations true -o teste.owl

Unfortunately does not work, for two reasons:

1. It is tied in with repair, which I may or may not want to run. I just want to merge axiom annotations
2. In the test ontology provided in this issue here, it drops the axiom annotations for new reason I can understand

Resulting ontology of the above command, and the test in the third comment of this issue
