Add mka support

[Dalan94]

Bug/Feature description

The mka (Matroska) container is currently not supported. It can handle any format and support chapter so it permit to store audiobook in one single file which is great.

Here is the trace when I try to import it:

During handling of the above exception, another exception occurred:

Matroska/WebM + Opus + Chapters + Cover image - it is the best open standard and quality solution for audiobooks. I want cross-post for some thoughts: https://github.com/PaulWoitaschek/Voice/issues/619#issue-238330181 http://zderadicka.eu/opus-audio-codec-for-audio-books-and-more/ https://kodi.wiki/view/Audiobooks#Resume_Points
