New release: Fuzzy dates (Patreon)

While working on some Multiposter extensions I noticed that I've needed a way to fuzzily parse a date input multiple times before, so I decided to factor that out and broaden it a bit into this library. There already is a library out there called cl-date-time-parser, which offers fuzzy parsing of some formats, but does not include relative time parsing, a use-case that's quite important to me.
