Improved codemeta parser, usage harvesting, user, DOI updates

This release includes an updated codemeta parser which is a bit more forgiving to alternative codemeta variants. It includes a set of scripts to harvest usage from matomo, parse according to COUNTER specifications, and add back into CaltechDATA. It is updated to work with version 0.1.3 of caltechdaata_api and pass back user information. It also includes a more flexible DOI metadata update capability that can handle different DataCite usernames and prefixes.
