Consistency btwn CSV ingest and update

[ekemeyer]

As a user, I want there to be consistency across the fields/columns used in the ingesters. For example:

• Asset.description is a valid column for the AAPB CSV Ingester, allowing for descriptions to be added without a type. However, it is not a valid column for the AAPB CSV Asset Attribute Update Ingester.

The above limitation has caused an issue with cataloging materials post-digitization, when additional descriptions become available. An example: https://ams2.wgbh-mla.org/concern/asset_resources/cpb-aacip-191-300zpg4s.xml.

<pbcoreDescription>No description available</pbcoreDescription> had been used as a placeholder until more information could be added. Ideally the cataloguers would have the option of batch updating or deleting this tag.
