[MINDEXER-231] The sha256 and bundle license fields appear to be empty for all artifacts in the maven index from Maven Central indexes

The sha256 and bundle license fields appear to be empty for all artifacts in the maven index from Maven Central indexes. Is this on purpose, is the data not being parsed/stored correctly, or is Maven Central just choosing not to divulge this information?

No further details from [MINDEXER-231](https://issues.apache.org/jira/browse/MINDEXER-231?redirect=false)

Start by reviewing MINDEXER-231 and the Maven Central index handling described there; the payload names no files, tests, or entry points. Done means determining whether sha256 and bundle license fields are intentionally absent or are failing to be parsed or stored.
