Struct AudioListenerNode 

pub(crate) struct AudioListenerNode {
    channel_info: ChannelInfo,
    position_x: Param,
    position_y: Param,
    position_z: Param,
    forward_x: Param,
    forward_y: Param,
    forward_z: Param,
    up_x: Param,
    up_y: Param,
    up_z: Param,
}

AudioListeners are fake nodes; from the user’s point of view they’re a non-node entity with zero inputs and outputs, but with AudioParams that can be manipulated.

Internally, PannerNodes all have an implicit PortIndex::Listener connection from a hidden output port on AudioListeners that contains all the position data.

This encodes the otherwise implicit dependency between AudioListeners and PannerNodes so that if there is a cycle involving panner nodes and the audio params on the listener, the cycle breaking algorithm can deal with it.
