What is it?

This daemon is used to control system microphone via AirPods button.
You need to double click button to toggle mute.
This will work in HFP/HSP profile. For example if you are in a Zoom/slack/WhatApp call, so you can click button on your AirPods to mute yourself.
This is POC, but it works very well ;)
