A simple event notifier to pub sub between Domain driven layers

use it with few simple steps:

1. Simply register the event notifier on the container in the setup file using services.AddEventNotifier()

2. Create a notification that is inherited from EventNotifier.Notification or just use Notification it self.

3. Create a subscriber on that Notification:

   notifier.Subscribe((SendHelloWorld notification) =>
             {
                      Console.WriteLine(notification.Data);
              });
   

4. Inject IEventNotifier and publish your message to the world!

   private readonly IEventNotifier _eventNotifier;
   public MicrosvcService(IEventNotifier eventNotifier)
   {
        _eventNotifier = eventNotifier;
    }
   
   public void SayHelloWorld()
   {
        _eventNotifier.Publish(new SendHelloWorld {
        Data = "hello my dear world"
        });
    }
