Duplicate and mispelled words cause strange bugs

[Aphexus]

If there is a duplicate or misspelling then things like definition, synonyms, and such will not include the duplicate and this will create a size mismatch between the passed wordlist and the output defs, syns, etc.

Simply doing list(set(wrds)) solves the issue with duplicates but one should likely duplicate the entries to match the inputted words.

Hi @Aphexus, interesting issue. Can you please create a PR with any new enhancements you might find? I'd appreciate any contribution to improving this library. Thanks!
