Reconcile people with identifiers

[osma]

Currently people mentioned in e.g. 100 and 700 fields are converted to resources by marc2bibframe and there is no reconciliation, so there is lots of duplication even from within the same MARC record. We should instead link to URIs for people in the output.

The problem is that currently we don't have the person authority record IDs in the bibliographic records. This is being worked on on the Aleph side. Probably it makes sense to wait for that instead of doing our own reconciliation.

[osma]

Now we have the first batch of person authority IDs in the Aleph bibliographic records.

[osma]

The first step would be to use URIs generated from the authority record IDs for the people, instead of blank nodes or URIs generated from the bibliographic record ID.

[osma]

Should also do this for person subjects (600)

[osma]

In future we should use the authorized names from the person names authority (like we do with CN) but for now this approach should be enough to get reasonably clean data for publishing

[osma]

Created a separate issue for the authorized person names. Other than that, this is done.
