[Feature Request] Volume change listener

[stereodenis]

What is the need and use case of this feature?
I have getVolume and setVolume methods, but no listener for remote volume change: from hardware buttons and notification widgets.

Describe the ideal solution
Add such listener to the package.
// listen the volume changing if you need

const volumeListener = TrackPlayer.addVolumeListener((data) => {
    const volume = data.value;
    console.log(volume);
});

//remove listener when you need it no more
TrackPlayer.removeVolumeListener(volumeListener)      

Describe alternatives you've considered
You can reffer to react-native-system-setting@alpha

How I can Help
I can be a beta-tester

We'll see if @dcvz thinks this should make it into the API. One thing I can say however, is that unless you plan on being a champion and doing some implementation, it's probably not going to get implemented by the core team. There are a lot of other feature requests and library needs and I don't see this falling near the top of the core team's priorities.
