Add audio capture capability to Mettle

[pbarry-r7]

Heyya @timwr...! We're looking to add audio capturing to Mettle (specifically with an eye toward improved streaming of audio back to the MSF instance instead of the current 15-second capture behavior or Meterpreter). I wanted to coordinate with you and make sure that this was something you weren't already working on and that it sounded, to you, like a good thing to add.

Thanks! 👍

This would be awesome. I'd love to help but I'm not actually sure how to do it. I can help out with testing and on implementation​ on other platforms (android)? I haven't looked at it yet on mettle/linux/osx though

Cool! @dmohanty-r7 and I will poke on it with the first goal of getting it working with simple, uncompressed audio, with the expectation of later circling back and pulling in a library geared for compressing speech for low-latency streaming.
