UNSTABLE: New API, yet to be vetted.
Unstable options which can be set when opening a datagram listener via
Deno.listenDatagram.
optional
reuseAddress: boolean = false
When true the specified address will be reused, even if another
process has already bound a socket on it. This effectively steals the
socket from the listener.
optional
loopback: boolean = false
When true, sent multicast packets will be looped back to the local socket.
