 Summary of the bug:
 ffmpeg contains ape decoder which can not properly handle 24bit
 How to reproduce:
 latest Monkey audio cli 5.55

 MAC.exe cut.wav cut.ape -c5000

 MAC.exe cut.ape cut_mac.wav -d

 ffmpeg.exe -i cut.ape -c:a pcm_s24le cut_ffmpeg.wav

 cut_mac.wav - equals to source cut.wav
 cut_ffmpeg.wav - contains garbage

 ffmpeg version N-99456-g45070eec4c Copyright (c) 2000-2020 the FFmpeg

 It seems ffmpeg contains outdated apedecoder which unable to handle non
 16bit properly.
