Oddesey TIB Mod for W3 control heads

The Oddesey tibs are ALMOST pin-compatible with W3 control heads, except that the AUX_MIC pin has been replaced with a VIP pin. This sucks, because without the MIC input, the head works otherwise, but there is no audio when the radio is keyed!

TODO: Guide on how to switch pin back to AUX_MIC function.
