[REQ] Display full time of downloaded book

[icetbr]

It would be nice to check if everything was downloaded. You could extract the duration from the site and show both of them on the terminal.

I use this command for example:

date -d@$(for file in *.mp3; do ffprobe -v error -select_streams a:0 -show_entries stream=duration -of default=noprint_wrappers=1:nokey=1 "$file"; done | paste -sd+ | bc -l) -u +%H:%M:%S

which gives 13:22:41 and the site has 13 hours

I leave here this code also in case anyone want to check manually.
