Doesn't work on macOS

[b5i]

Hello ! When I run this program with a mp3 file I get the following error :
ws.schild.jave.EncoderException: java.io.IOException: Cannot run program "/var/folders/gj/7wnvhh_92fn2cs9thjy0t0y40000gn/T/jave/ffmpeg-x86_64-3.2.0-osx": error=2, No such file or directory

We don't yet support macOS. I added a note to the README. I'm leaving this issue open though, because we're working on it!
