Enable use alias in annotation

use Dingo\Blueprint\Annotation as BP;
use Dingo\Blueprint\Annotation\Method as BPM;

/**

• @bp\Resource("Test")
  /
  class TestController extends Controller
  {
  /*
  • Ask for new service
  • @bpm\Get("/test")
  • @bp\Versions({"v1"})
    */
    public function test(){
    }
    }

Would definitely like to be able to use namespace aliases. And as far as I can see, that is not possible with the SimpleAnnotationReader. However, perhaps this PR should be changed to have Blueprint depend on the Reader interface and have the actual implementation class configurable. Neater in general an perhaps the motivation for using SimpleAnnotationReader was for performance reasons?
