Removed innecesary function to convert subtitles, improved use of the youtube api
Only works in youtube for the moment.
Improved option '--srt-lang' - it shows the argument in case of missing subtitles - added language suffix for non-english languages (e.g. video.it.srt)
This made the JSON structure really unreadable and was a quick fix. This reverts commit 6535e9511f.
