Sometimes IIIF image servers limit the dimensions of the largest "full" image they make available (so people can't just download the full-res version); the code to highlight the detected handwriting regions via IIIF annotations now handles these situations.
There's a new command-line option, --max_pages=N, which can be used to avoid processing all of the images/pages on a given manifest, if for example the manifest is really long and you only want to detect handwriting on the first N pages.
The generated IIIF annotations have been streamlined considerably, thanks to suggestions from @glenrobson.
