bugfix: inputs/.TNRS/schema.sql: taxon_match: use "Accepted_species[_binomial]__@TNRS__@vegpath.org" instead of "*Accepted_name_species". this fixes a bug in __accepted_infraspecific_label where Accepted_name_species with trailing whitespace could not be prefix-removed from names that contained just a species binomial.

fix: inputs/.TNRS/schema.sql: taxon_match: added derived column "Accepted_species[_binomial]__@TNRS__@vegpath.org", which removes trailing whitespace

inputs/.TNRS/schema.sql: added steps to remove a column and to add a non-derived column

inputs/.TNRS/schema.sql: taxon_match: to remove columns or add columns at the end: merged into "to add a new derived column"

inputs/.TNRS/schema.sql: to add columns in the middle: renamed to "to move a column to the middle" for clarity

inputs/.TNRS/schema.sql: to populate a new column: updated to use util.derived_col_update()

fix: inputs/.TNRS/schema.sql: taxon_match: to remove columns or add columns: also need to run util.recreate_view()

inputs/.TNRS/schema.sql: taxon_match: to remove columns or add columns at the end: don't need to run `rm=1 inputs/.TNRS/data.sql.run` because this is now run by `make schemas/remake`

inputs/.TNRS/schema.sql: added new derived columns to derived views

schemas/util.sql: remove_prefix(), remove_suffix(): support case-insensitive matching
