taxize v0.9.94

NEW FEATURES

• synonyms() gains a method for Plants of the World Online (synonyms.pow); and new associated helper function pow_synonyms() used within synonyms.pow (#812)

MINOR IMPROVEMENTS

• change to iucn_summary() to allow get_iucn() failures and the function to still proceed - to make a better experience when passing in more than 1 name (#810)
• fixed non-ASCII string in the species_plantarum_binomials dataset

BUG FIXES

• classification() for data source GBIF wasn't working when the queried taxon rank was below species (e.g., subspecies or variety); GBIF didn't return the same fields for ranks below species, so we tack on that information with a bit of extra code (#809)
• fix sorting of results in classification() with data source GBIF; at some point introduced bug in how results were sorted (#811)
