Productionize polished cosmoaudio library

Browse source 
This change introduces comsoaudio v1. We're using a new strategy when it
comes to dynamic linking of dso files and building miniaudio device code
which I think will be fast and stable in the long run. You now have your
choice of reading/writing to the internal ring buffer abstraction or you
can specify a device-driven callback function instead. It's now possible
to not open the microphone when you don't need it since touching the mic
causes security popups to happen. The DLL is now built statically, so it
only needs to depend on kernel32. Our NES terminal emulator now uses the
cosmoaudio library and is confirmed to be working on Windows, Mac, Linux
