Support multipage PDFs

[samhenrigold]

Multipage PDF support would be a game changer for me. In a Node script I'm writing, I have to split PDFs into individual images and run the OCR utility over each page. This introduces a fair amount of hanging while my computer has to render each page in the background before passing it to text-cli.
