This feature will not activate the selected protocol unless a bind is
requested using bind from channel or the GUI "Bind" button. It is only
enabled if bind from channel and autobind are set since I think they are
working well together.
The goal is to prevent binding other people's model when powering up the
TX, changing model or scanning through protocols.
There is a new blinking pattern associated to it as well as a new status
"Waiting for bind".
This feature is enabled by default in _config.h .
