Need a way to identify the clients of a WebsocketServer

[RnMss]

For now I haven't found a way to match a Websocket& with the std::set<std::shared_ptr<WebSocket>>,
from the client message callback void(std::shared_ptr<ConnectionState>, WebSocket&, const WebSocketMessagePtr&),
and get clients std::set<std::shared_ptr<WebSocket>> getClients() respectively. I can not tell the clients from getClients from each other, this is necessary when you want to send message asynchronously.

For now the only workaround I know is address comparison, which is not a real solution. Since there is an unegligible chance that a newly allocated Websocket object takes the place of a previously free-d one (in the heap), so they'll have the same address.

I guess this can be done by changing the OnClientMessageCallback to std::function<void(std::shared_ptr<ConnectionState>, std::shared_ptr<WebSocket>, const WebSocketMessagePtr&)> (replace reference with shared_ptr). The shared_ptr can be converted to a weak_ptr for long-term storage. This is a breaking change, though.

I think the real way is to have client connection authenticate, and then associate them with a user id or equivalent.
