Add --audio-streams flag to configure number of audio streams for .ts output

Browse source 
Since videos with translations appear to require at least as many audio
streams in the intro/outro as there are audio streams in the main video,
this allows to create intro/outro files for videos with more than one
translation (so far, the code already created 2 streams).
