Feature: support for useTrackVolume

[leethree]

Is your feature request related to a problem? Please describe.

We are trying to use the SDK to create a voice call experience. But there doesn't seem to be a way to get the real time track volume levels from the SDK. Use useTrackVolume directly from @livekit/components-react shows the following error:

Error: Audio Context not supported on this browser

Apparently it's using a web API that's not supported in React Native. So it's difficult to build a great audio experience that gives the user real-time visual feedback.

Describe the solution you'd like

It would be greatly helpful to have support for this hook.

Describe alternatives you've considered

Daily.js has this feature in their React Native SDK. I believe they are also based on React-native-webRTC

Additional context

Any workaround is greatly appreciated as well.

Did you manage to find a workaround? Running into a similar need for an UI / UX we're building.

we are working on this.. planning to have audio level exposed to RN along with audio visualizer components.

This is vital to deliver a good UX. I wouldn't even need the components. Just being able to subscribe to audio level would be enough. Going to try and find a workaround in the meantime and will share.
