No provision for passing metadata inside directives.

[nidhinsg22]

I want to show some titles and images while the audio is getting played. If I am able to pass the metadata directives under directives key after audioItem key then it can be done. But I think this gem won't support passing this metadata tag. It only supports normal cards.
