Read a title's HTML entities as the characters they stand for

An Atom title of type="html", and an RSS title in CDATA, reach the parser
with their entities intact, so The Verge's "Meta’s" showed as typed:
55 stored titles across 17 feeds. Titles are decoded one entity at a time
with quick-xml's HTML5 table, leaving an & that starts none ("Q&A") alone
rather than failing the whole title.
