using this tool and chaptered mode, ffmpeg fails out with
[libx264 @ 0x5588ef28d780] width not divisible by 2 (483x500)
Error initializing output stream 0:1 -- Error while opening encoder
for output stream #0:1 - maybe incorrect parameters such as bit_rate,
rate, width or height
Conversion failed!
This is because the cover file embedded in the downloaded mp4 file
from Audible has the dimensions 483x500. Found the extra_crop_cover
that's currently being used only for covers from the Audible CLI
tool and extended the script to instead check the dimensions of the
cover file and include the extra_crop_cover anytime the cover has an
odd width.
