initial importHEADmaster

currently everything is very tied to alsa and my system,
for the moment you'll need to manually change the device names
and maybe channels/period_size in src/main.rs, src/bin/smolguitar.rs
and src/bin/loopbacker.rs, i'll fix that and add runtime period
size/updater allocation soon, (and probably make a cpal backend as well
so it can work on other platforms), but doing this initial commit to play
around with stereo for now~
