inputs/.TNRS/schema.sql: Removed no longer used tnrs+accepted. Use tnrs_canon or a self-join of tnrs instead

schemas/vegbien.sql: tnrs_input_name: Use TNRS.tnrs directly instead of the now-deprecated tnrs+accepted

schemas/vegbien.sql: Use new TNRS.tnrs_canon instead of tnrs+accepted to avoid creating additional taxonlabels for the parsed, matched, and accepted names and instead just use the most-canonicalized name of the names output by TNRS (the accepted name if available, or the matched name otherwise)

mappings/VegCore-VegBIEN.csv: "if has verbatim name" _if statements that filter something out for TNRS mappings: Also assume true if taxonIsCanonical is specified, because some TNRS tables (eventually such as public.unscrubbed_taxondetermination_view) do not specify a separate "verbatim" taxondetermination but do provide taxonIsCanonical as a flag to turn various mappings on and off

mappings/VegCore-VegBIEN.csv: Remapped matched*Fit_fraction to taxondetermination.taxonfit when a taxondetermination, not just a taxonlabel, is provided

bin/map: map_table(): Resolving prefixes: Fixed bug where need to use list instead of tuple for metadata value mappings

schemas/vegbien.sql: taxondetermination: Added CHECK constraint to allow only taxondeterminations with a minimum fit fraction of 80%, analogous to taxonlabel's taxonlabel_1_matched_label_min_fit() trigger

mappings/VegCore-VegBIEN.csv: Don't create a separate TNRS input taxonlabel if taxonIsCanonical exists

inputs/.TNRS/schema.sql: tnrs_canon: Fixed bug where need to always use Unmatched_terms from tnrs rather than tnrs_accepted

inputs/.TNRS/schema.sql: Added tnrs_canon, which stores the most canonicalized name output by TNRS
