[feature request] Determine duplicates based on match code.

[adam-rudd]

Works super well, nicely put together.

I came looking for it, because the built in plex duplicate finder had limitations. It would be nice to scan, or maybe I'm missing how, to scan based on whatever the 'tmdb' or 'imdb' match code is. Inspite of editions/versions/etc. Video file comes in, gets auto named as a different 'edition', but is not seen as a duplicate. Sometimes want to keep the older edition, sometimes not.

e.g. these are not seen as duplicates even though the edition one effectively replaces it. this isn't an always thing. User needs to decide when to keep multiple editions or not.

Movie {tmdb-1234}
Movie {tmdb-1234} {edition-imax}
