Thanks! Just a few things to do but I will get this merged in. Worked on the CM108 interface for my AIOC cable :) |

Added basic support for PTT using GPIO pins of the CM108 USB audio IC.
This IC is a popular choice for basic PC <=> Radio interfaces and is used in projects such as the AIOC (https://github.com/skuep/AIOC), which emulates a CM108 audio interface.
This PR adds a fifth PTT option, "CM108" and it's associated GPIO pin selector (1-4, 3 as default as it's the easiest to solder on commercial USB audio sticks). These options can be set in the gui or with --ptt cm108 --cm108-gpio 3
The only major limitation I see if several CM108 audio interfaces are plugged in. I'll add this "advanced" (be able to target a particular CM108 interface) support later.
