Asynchronously calls method with params on the remote peer.
This function will not wait or expect a reply from the peer.
This function is useful when the caller wants to be notified that the bytes have been delivered to the underlying stream. This does not indicate that the peer has received them.
If params is floating then the reference is consumed.
