Add node bindings with example usage

[stevenlafl]

Here are some node.js bindings. Example usage is provided like your other bindings, using prism-media like the Discord.js/voice package does. Let me know if the output lines up with what you're expecting..

Here's with the example running against your zoo.wav, it's converted to PCM16 using ffmpeg.

 ALL RIGHT SO HERE WE ARE ON THE ELEPHANT COOL THING WHAT THESE GUYS IS THAT THEY HAVE REALLY REALLY REALLY LONG PROMISE AND THAT'S THAT'S COOL

Hi, thank you for the contribution! Could you change the examples such that the paths can be input by the user and are not hardcoded?

[stevenlafl]

@abb128 I've added that feature to the example.
