Add an axiom swapper command

This would be useful both for GO-Rhea, but also for complex dosdp workflows.

Possibly implement as a robot command? Or specific to dosdp?

Inputs: two ontologies (src, tgt) plus configuration that can be used as an axiom filter

For every axiom in src, if axiom matches filter, then inject axiom into tgt. For a subset of these, this will be a replace operation.

Example: GO needs to do updates on MF terms based on Rhea, where we replace GO text defs, GO xrefs (other that the Rhea xref itself) and potentially is-as with the Rhea equiv (to implement this we could have a special OWL version of Rhea that uses GO IDs as primary)

No implementation files, tests, or entry points are named. Start by surveying the existing command structure and how dosdp-tools handles ontology inputs and filters. Done would require a decided command scope, defined source-to-target axiom behavior, and coverage for the proposed replacement cases.
