The Flutter driver helpfully logs ALL messages to the stderr output
useless something is listening to the messages.
This reporter listens to the messages from the driver so nothing is logged
to the stderr stream unless it is actually an error.
This can cause problems with CI servers for example as they will mark a process as failed if it logs to the
stderr stream. So Flutter driver will log a normal info message to the stderr and thus make
the process fail from the perspective of a CI server.
Pauses the execution for the provided number of seconds.
Handy when you want to pause to check something.
Note: this should only be used during development as having to pause during a test usually indicates timing issues
