schemas/vegbien.sql: unscrubbed_taxondetermination_view: Do the tnrs_canon joins manually instead of using tnrs_canon, to allow PostgreSQL to use a nested loop join on just the needed tnrs rows instead of a hash self-join of all tnrs rows. The query planner is not yet advanced enough to automatically integrate the select on the view into the top-level joins list, which would make this change automatically.
