The get stream is broken on [email protected].

There are have been 2 commits to master since the last release -- I'd like to be able get them when I require s3scan: v0.2.0...master

It would be a nice thing to do for your bucket's well-being.

Sometimes it appears that the aws-sdk can return no error object, and also provide a data object where .Contents is undefined. In that case we would throw an unhandled error in the callback when we try and .slice the anticipated array.

s3.listObjects(params, function(err, data) {
  assert.notOk(err, 'there is no error');
  assert.notOk(data.Contents, 'there is also no information');
});

It would be cool to have a cancel method. Right now I'm using this to pipe an s3scan.Scan to another transform stream, and then when I've gotten as much as I need I end that stream, but trying to end the scan stream results in a write after end error because of the queue. Something like a purge or cancel option to delete all queued items and cancel the stream would be useful in cases like this.
