Pop-up bubble/balloon notification (feature request)

[Damian-2001]

It is not so difficult to add this option, I share in case it can help someone.
*Note that on windows >= 10 , "balloon notifications" is equal to "toasted notifications" and they can be implemented in addition to Shell_NotifyIcon, with WinRT api

traybar.py

        if onclick and "function" in repr(onclick):
            self._balloon_callback = onclick
