Add warning output to Fletchgen for unused metadata fields #246

Closed mbrobbel closed 1 year ago

It would be helpful to have Fletchgen output warnings for unused metadata fields that start with fletcher_. For example, (this happened to me) when someone adds fletchgen_epc to Schema metadata instead of Field metadata.
