+Goal is to make sure we have imported all in-scope crossref DOI objects. There
+were a few months gap between the snapshot used as initial bootstrap and the
+start of continuous ingest; any DOIs registered during that gap and not updated
+since are not in fatcat. Expectation is that this will be a relatively small
+import.
