Scala 2.13: `ScalaRunnableWrapper` uses `akka.dispatch.Batchable`

[iRevive]

Hello! Thanks for the awesome library.

I have a question regarding ScalaRunnableWrapper for Scala 2.13:

akka-sensors/sensors-core/src/main/scala-2.13/akka/sensors/dispatch/ScalaRunnableWrapper.scala

Lines 3 to 16 in 82f28d1

	import akka.dispatch.Batchable
	import akka.sensors.dispatch.DispatcherInstrumentationWrapper.Run
	import scala.PartialFunction.condOpt
	object ScalaRunnableWrapper {
	def unapply(runnable: Runnable): Option[Run => Runnable] =
	condOpt(runnable) {
	case runnable: Batchable => new OverrideBatchable(runnable, _)
	}
	class OverrideBatchable(self: Runnable, r: Run) extends Batchable with Runnable {
	def run(): Unit = r(() => self.run())
	def isBatchable: Boolean = true

According to the code, the match expects the akka.dispatch.Batchable type. Then, AkkaRunnableWrapper relies on akka.dispatch.Batchable too.

akka-sensors/sensors-core/src/main/scala/akka/sensors/dispatch/InstrumentedDispatchers.scala

Line 61 in 82f28d1

case runnable: Batchable => new BatchableWrapper(runnable, _)

If I get it right, the case case ScalaRunnableWrapper(runnable) => runnable(r) will never happen.

akka-sensors/sensors-core/src/main/scala/akka/sensors/dispatch/InstrumentedDispatchers.scala

Lines 106 to 111 in 82f28d1

	def apply(runnableParam: Runnable, r: Run): Runnable =
	runnableParam match {
	case AkkaRunnableWrapper(runnable) => runnable(r)
	case ScalaRunnableWrapper(runnable) => runnable(r)
	case runnable => new Default(runnable, r)
	}

I assume, ScalaRunnerWrapper should import scala.concurrent.Batchable instead?
