Updated error handling and ORCID mapping

What's Changed

• Improved DOI harvesting for all harvests by splitting up the process in the GitHub action. The action now lists all DOIs and their status individually, and returns a failure state only when there is an system error. Skipped DOIs are labeled in red, but this does not result in the harvest being labeled as failed.
• The harvester now looks for individuals already listed in CaltechAUTHORS by their ORCID identifier and pulls their affiliation and local identifier into the record.

Full Changelog: v0.1.0...v0.2.0

Initial release of irdm_harvester

This is the initial release of the irdm_harvester application. It's the version we're currently using in production to send content to CaltechAUTHORS, and includes CrossRef and ORCID support. While there are still improvements to be made, the base functionality is solid.
