Battery voltage telemetry mod for FlySky ia6b receiver

By default the ia6b receiver returns telemetry info showing the voltage of the receiver itself - which is not that useful when the receiver is running off a BEC powered by the main flight battery. Cutting some traces and adding a wire lets you use that telemetry for an external voltage.
