Feature request: include ownerOperator + year in aircraft.json

[thecowan]

Just wondering if it would be possible (either controlled by the --db-file-lt, if we treated that as just 'detailed registration output', or perhaps another separate flag) for the aircraft.json output to also include the operator + year fields from the DB, if present (ownOp and year)? This would be useful information for me to visualize in a project of mine.

Thanks so much!
