title: Creating a Source out of an EventStream
body: <p>I am using PlayFramework 2.5.3 and would like to create an <code>akka.stream.scaladsl.Source</code> from an <code>akka.event.EventStream</code> (the eventstream is part of an actor system). The event stream would produce events from a certain type, so I would need to subscribe to that certain type of events and push them by using <code>play.api.mvc.Results.chunked</code>. Is there any easy way to create such a <code>Source</code> using Akka Streams 2.4.5?</p>
