when making prediction, return bool indicating whether image was resized or not

Will be helpful for the API, and also to display on our front end. If too much resizing was done, results might not be accurate. We don't need to actually say that - we just say this image was resized.

No sure anymore if this makes sense, since a pre- or postprocessing could do any kind of funky stuff to the image the user might not be aware of and which might affect results. Hence I would not provide such info via the API. A good model would have these details explained in the model's documentation, but that's of course up to the contributor.
