Built-in AirPlay Support

[codybrom]

Is your feature request related to a problem? Please describe.
While I can technically play the ambient sounds through AirPlay by routing all system audio that way, it's not ideal. It would be much better to have built-in AirPlay support within the app, so I can send only the ambient sounds to my chosen speakers, like my Sonos, without affecting other system audio.

Describe the solution you'd like
I'd love to see AirPlay integrated directly into the app. This would allow me to select my AirPlay speakers and devices, including my Sonos speakers, from within the app's interface and stream the ambient sounds directly. Multi-room support would be a welcome bonus.

Describe alternatives you've considered
As mentioned, routing all system audio through AirPlay works, but it's a clunky workaround. It means any other sounds from my Mac also go to the AirPlay device, which I don't want.

Additional context
Built-in AirPlay integration would significantly streamline the experience and provide more control over audio output. This is a useful feature in other audio apps and would make this app much more useful for people with AirPlay / Sonos speakers!
