awaitStopAsync

Delays the current coroutine until the Stdio.Pipe stops producing output.

Does nothing if:

• Stdio was not Stdio.Pipe

• No OutputFeed were attached before Process.destroy was called (i.e. never started)

• Has already stopped

NOTE: For Jvm & Android the kotlinx.coroutines.core dependency is needed.
