[~bkietz] is there any code samples on how to do that? Looking to use the new dataset api.

> This will allow in memory datasets (such as tables) to participate in discovery through {{UnionDatasetFactory}}. This class will be trivial since Inspect will do nothing but return the table's schema, but is necessary to ensure that the resulting {{UnionDataset}}'s unified schema accommodates the table's schema (for example including fields present only in the table's schema or emitting an error when unification is not possible)
