[node-ws] Pass the original close code (currently, it's always 0)

[moroshko]

Which middleware is the feature for?

node-ws

What is the feature you are proposing?

Currently, it looks like when the CloseEvent is created, the close code is not specified, resulting is event.code always being 0:

onClose(event) {
  console.log("Close code", event.code); // always 0
}

Can we pass the original close code to onClose()?
