@mattyb149 Looks like a lot has changed in the last 9 months.
The code I added here leveraged classes related to Schema registries, but
those classes have been moved into a more Avro specific package
(`nifi-avro-record-utils`), where the CSV stuff is still under a standard
package (`nifi-standard-record-utils`). Looks like it'll take some work to
abstract the schema-registry specific stuff away from Avro, so the CSV
reader/writers can leverage it.
Sadly, I don't have the time to get back deep in NiFi right now, so I'm OK
with closing this PR so a more updated solution can be worked on.
