inputs/VegBank/taxonobservation_/create.sql: join starting with taxoninterpretation so that we can use the taxoninterpretation_id as the row_num (text strings, formed from concatenated #s cannot be used as a row_num). there is only 1 taxonobservation without a taxoninterpretation, so we can just include one row for each taxoninterpretation.
