Additional example: saving voice data

[luttje]

Hi there, thanks a bunch for sharing this awesome module!

I thought I'd share a short example based on your voice-relay example:

gmod-voice-chat-recorder example

This example saves voice data to .wav files. This can be useful for server owners that want to moderate voice-chat, even when they're not online. That's what I'll likely be using your module for.

I saw an issue of someone being confused how to use your module, so thought another example might help others.

Thanks again!
