Feature: Ability to specify page range from where to extract annotations

[indicatorvariable]

Use case 1: Sometimes, we may need annotations from just a specific chapter or a few pages from here and there. This would also speed up the extraction process as all pages need not be processed. Use case 2: New annotations are being made as one progresses through the pdf, and hence needs to process only the newer annotations.

Thanks for the suggestion. This is not an unreasonable request, but it's not my use-case so please don't hold your breath too long waiting for me to build it :)
