BUG FIXES

• wt_wikicommons() fails better now when a page does not exist, and is now consitent with the rest of package (#14)
• wt_wikicommons() fixed - classification objects were not working correctly as the data used is a hot mess - tried to improve parsing of that text (#13)
• wt_data() fix - was failing due to i think a change in the internal pkgWikidataR (#12)
