Make a note that the facade needs to be aliased

[Sairahcaz]

Thanks for this great package!

I think it is a good idea if you would mention somewhere that the facade needs to be aliased.
It would have helped me if I had seen it on the readme. All the examples are without the facade alias.
So it was a bit confusing for me...

use hisorange\BrowserDetect\Facade as Browser;
