How Can I Get Websocket Timeout Err Message Or Event

Hey Bro, Thank you for your project.

Is there a way to get errors? When the client disconnects, let me know whether it is a timeout disconnection or something else

```go
ws := websocket.New(gorilla.Upgrader(
gorillaWs.Upgrader{CheckOrigin: func(*http.Request) bool { return true }},
), websocket.Events{
websocket.OnNativeMessage: func(nsConn *websocket.NSConn, msg websocket.Message) error {
Listen.WS = nsConn.Conn.Server()
Listen.Ctx = websocket.GetContext(nsConn.Conn) //todo
Listen.Get(msg, nsConn.Conn.ID())
nsConn.Conn.Socket().NetConn().SetReadDeadline(time.Now().Add(1 * time.Minute))
return nil
},
//websocket.OnAnyEvent 不可用
})
ws.FireDisconnectAlways = true

ws.OnUpgradeError = func(err error) {
util.GetWsLog().Infof("设备连接失败 [%s]", err.Error())
}
ws.OnConnect = func(c *websocket.Conn) error {
util.GetWsLog().Infof("Websocket连接 [%s]", c.ID())
return nil
}

ws.OnDisconnect = Listen.onLeave

util.GetWsLog().Infof("websocketController:%p", Listen)
go Listen.RedisReadMsg()

app.Get("/ws", websocket.Handler(ws))
```

Start with the websocket.Events configuration and the OnDisconnect callback shown in the issue, then inspect how NetConn().SetReadDeadline interacts with disconnect handling. Done means documenting or exposing whether a client disconnect was caused by a timeout or another error, with the behavior covered for the shown websocket setup.
