Add shuffle and other options to media browser

[bernikr]

I really like that the usage of this integration improved drastically with the new media browser. However, I find myself still using the old spotcast.start service because I want to shuffle a playlist. I think if the there was a way to set the "shuffle", "random songs" and other flags through the media browser, the usability would improve even more.

This is sadly a limitation on home assistant side. Not possible to implement because the media selector doesn't have hooks for shuffle and random songs (for all I know, the documentation is very lacking for this feature).

Even then, the shuffle toggle would have to be implemented from the Spotify integration directly, not Spotcast

@fcusson the Spotify code seems to suggest it's there

@hmmbob the media_player does provide a way to shuffle directly from media_player.spotify, but the media_selector currently doesn't have the button for it. We only have access to async_browse_media and async_play_media. No argument can be passed to play_media and the media_selector only has a simple play button, no way to select to shuffle.

Unless I'm missing something in the documentation, but the only hook we have is the async_play_media.

Technically, we can modify the method to shuffle the media source, but that would be hardcoded and not something the user can choose.

That leaves us with hardconding the shuffle and random_song arguments or calling the service. We must ask ourselves:

1. Should shuffle be the default playback method or ordered should?
2. Could we parse per media_type and say per exemple, album is ordered but playlist shuffle?

The important part to take into account is that we would be forcing this behavior on all the users

[hmmbob]

Hmmm, too bad. Saw this in the code, so hoped it would be available for use.

I don't think existing behavior should change.

With mushroom cards it's a little buggy but works.
