Pass error code in Websocket InitFunc

[muku2211]

What happened?

For websockets, authentication errors in InitFunc, closes the connection with a normal closure (status code: 1000).
However, as defined here, for the ConnectionInit message,

Closing the socket with a close event 4403: Forbidden indicating that the connection request has been denied because of access control. The server has returned false in the onConnect callback.
Closing the socket with a close event 4400: indicating that the connection request has been denied because of an implementation specific error. The server has thrown an error in the onConnect callback, the thrown error's message is the in the close event.

What did you expect?

The ability to specify the close code for connection init i.e either 4403 or 4400 depending on the use-case and the ability to send a custom message. Currently, the string "terminated" is hardcoded in the library.
