KNOWN_ONLY constant

Ignores observed messages from foreign meshes like LOCAL_ONLY, but takes it step further by also ignoring messages from nodenums not in the node's known list (NodeDB)

Implementation

static const Config_DeviceConfig_RebroadcastMode KNOWN_ONLY =
    Config_DeviceConfig_RebroadcastMode._(
        3, _omitEnumNames ? '' : 'KNOWN_ONLY');
