Feature Request: Bluetooth remote control media buttons support

[Schaussi]

As mentioned in an older ticket (#117), it would be great to have some basic support of Bluetooth remote control hardware, e.g. for "Pofet Steering Wheel Bluetooth Remote" or similar.
I guess the remote is recognized as keyboard within Android. It works out of the box with e.g. the Youtube app, but unfortunately not with Squeezer.

For me, it would be enough if the Next button would work (Vol up+down are working).

Thank you!

I've been having a play with this and it's a bit of a bugger to resolve. I noticed it when I was out walking. I use SBPlayer as the sink for the music being streamed. It appears as just another player to be controlled. However because that is the app that is actually making noises, and not Squeezer, the media events go to SBPlayer and Squeezer never sees them. The ultimate solution may be to build an audio player into Squeezer but that is somewhat of a sledgehammer solution.

I'm currently experimenting implement media3, maybe this helps.
To embed an audio player into Squeezer is currently not in the pipeline, as there are alternatives. But pull requests are welcome, if anyone wants to pick it up!
