Add stereo reveivers into the list of supported connectable devices

[Yesmarc]

I loved listening to Spotify on my Onkyo TX-NR616 receiver which came with the spotify app installed. When Spotify removed this functionality on July 20th 2017 they did not add t into the list of devices that connect to iPhones. PLEASE. ADD IT IN!
I bought my receiver for this purpose and I am so sad it's not available at the moment. I hate listening to Spotify on my iPhone speaker again.
Thanks for listening.
