Map codemeta contributor to zenodo contributors (type "Other")

(It is understood that this is all a matter of definitions and interpretations ;) )

I propose this mapping change, because I would like to adopt the eossr-codemeta2zenodo tool. But with the current mapping I probably cannot use it. In our definition contributors spent significantly less time and resources on the project compared to authors. Usually, once a contributor reaches author impact levels, she gets promoted to author - those are the only two distinctions we have upstream.

I would be happy to put our codemeta contributors into a different category that is already mapped to zenodo's contributors list, but I have not found suitable fields (yet?). Open to suggestions.
