Duplicates with 1 second difference not removed

[truth1ness]

I ran dupe killer and it caught about a third of the duplicates in my account. However, there are hundreds of tracks that I uploaded that have an exact duplicate match of song name/artist/album but they are not removed because there is a 1 second difference in the song length. These were songs I imported from iTunes and so were probably trimmed slightly differently. But Dupe Killer should have an allowance for duplicates that are within 1 or 2 seconds of each other to account for this slight variance when importing songs.

First, great scripting peeps; this has genuinely fixed many of my duplicate songs in my Google Play Music library.

truth1ness is absolutely correct, however. I tried this just now while listening to an album with duplicate songs, half of which are 1 second shorter compared to the Google Play Music version (vaguely recall this 1 second trimming being an option some ppl may have employed with programs like Exact Audio Copy and --alt-preset-standard mp3 encoding... little did I anticipate this being such a headache many years later...oops?!).

Anyway; would you guys consider being god-like awesome and extending the kill_dupes.py script to be able to Dupe Kill tracks which are more than 98% of the same duration? (perhaps as a separate option...?)
