ipptransform: Copy Annots values from page dictionaries

[michaelrsweet]

When copying pages "manually" for things like N-up support, ipptransform needs to also copy the Annots dictionary to get any annotations/form data for a page as well.

Having some difficulties getting the N-up working, but normal 1-up works already. Pushing this to a later stable release.
