feat request: media player icon

[cjb0001]

Would you mind also adding the 16x16 icon attribute? I couldn't figure out how to reference the icon from the currently playing chapter/track.
It will need to be added as an "extra_state_attribute". Here are some examples of how other media_player integrations have done this. Seems like state check before returning the icon is the right thing to do.
Thanks

Are you looking for the track icon or the chapter icon? I haven't seen the difference in my yoto yet but maybe I don't have a card that has that.

For reference will be from here once we pick: https://github.com/cdnninja/yoto_api/blob/master/yoto_api/Card.py I don't think I populate track icon yet.

[cdnninja]

I have created the code to parse all the track and chapter data into the object listed above: cdnninja/yoto_api#59

That is first step. Next we can easily display that data.

[cdnninja]

#81 does this. Let me know thoughts on if this is what you were thinking. Right now track sometimes comes as "null" but it doesn't error out. Wondering if that is okay or if I should only return non null. It doesn't error or anything

[cdnninja]

I corrected this. It will now only show if data exists.
