Using go-sql-driver/mysql

It's able to use RegisterDial to connect wsgate-server.

mysql.RegisterDial("websocket", func(url string) (net.Conn, error) {
	wsURL := strings.Replace(url, "http", "ws", 1)
	wsConf, err := websocket.NewConfig(wsURL, url)
	if err != nil {
		log.Fatalf("NewConfig failed: %v", err)
	}
	conn, err := websocket.DialConfig(wsConf)
	if err != nil {
		log.Fatalf("Dial to %q fail: %v", url, err)
	}
	conn.PayloadType = websocket.BinaryFrame
	return conn, err
})

db, err := sql.Open("mysql", "yyyy:xxx@websocket(https://example.com/proxy/mysql)/test")
