Make startRecording() async

[Singe72]

I'm using DisTube for my project and the function to create a connection is asynchronous, so I'm forced to set a timeout because the connection is not done instantly. It would be cool if the startRecording() function was asynchronous 😄

I would not make a function async if it isn't needed.
If you want it async you could basically write

(async()=> {
  voiceRecorder.startRecording(...)
})();

// or
async function startRecording(connection: VoiceConnection): Promise<void> {
  voiceRecorder.startRecording(connection);
}

I'm still not quite sure about your use-case. If the create connection function is async, you can basically await it or start the recording inside the then(()=>...) of the Proimse.
