Add AbortSignal to prepareStream and playStream

[longnguyen2004]

Adding this because while working on https://github.com/Discord-RE/FFmpeg-input-premade, I came across some cases where ending the stream is a bit more complicated than just a single command.kill, and having a unified way to end processes would be better for other users.

AbortSignal is chosen because many other Node APIs and libraries are using it as the way to abort processes.

// Global variable
let controller = new AbortController();

const { command, output } = prepareStream(url, { ... }, controller.signal);
await playStream(output, streamer, { ... }, controller.signal);

// End everything
controller.abort();

Yes this looks good.

I like that AbortController will end both methods. I think that's better

Seems to work fine. Also we should release 5.0.0 after this
