Convert YouTube subtitles(vtt) to human readable text.

Download only subtitles from YouTube with youtube-dl:
youtube-dl  --skip-download --convert-subs vtt <video_url>

Note that default subtitle format provided by YouTube is ass, which is hard
to process with simple regex. Luckily youtube-dl can convert ass to vtt, which
is easier to process.
