Function: A WebSocket task can be created with a ws or wss url.
Notes:
A client can also provide a list of protocols it wishes to advertise during the WebSocket handshake phase.
Once the handshake is successfully completed the client will be notified through an optional delegate.
All reads and writes enqueued before the completion of the handshake will be queued up and executed once the hanshake succeeds. Before the handshake completes, the client can be called to handle redirection or authentication using the same delegates as NSURLSessionTask. WebSocket task will also provide support for cookies and will store cookies to the cookie storage on the session and will attach cookies to outgoing HTTP handshake requests.

Available on MacOS 10.15 or newer.
Subclass of the NSURLSessionTaskMBS class.
This is an abstract class. You can't create an instance, but you can get one from various plugin functions.
