Akka versions compatibility

Please note that while the library depends on Akka 2.4.x is fully compatible to be used with Akka 2.5.x. This is because of Akka's strict backwards compatibility guarantees. If you want to use reactive-kafka with Akka 2.5 simply include Akka and Akka Streams dependencies using the latest 2.5 version, for example like this:

libraryDependencies += "com.typesafe.akka" %% "akka-stream" % "2.5.x" // pick the latest version here
libraryDependencies += "com.typesafe.akka" %% "akka-actor" % "2.5.x"

Note that it is important that all akka-* dependencies are in the same version, so it is recommended to depend on them explicitly to avoid problems with transient dependencies causing an unlucky mix of versions.
