Stream packer.py output to console

[Arlington1985]

Currently, you can't see the output of packer.py unless it finishes its job. Is there any way to stream it in real-time to console?

The constructor accepts a config kwarg where we can set the stdout & stderr handlers given to the packer subprocess. I'm running this in a container for drone, and this execution is working for me:

packer = PackerExecutable(
    machine_readable=False,
    config=dict(
        stdout=sys.stdout,
        stderr=sys.stderr
    )
)

Thanks for assuring me I wasn't the only one.
