Linearize PDF API

Restructure a PDF so the first page displays before the rest of the file finishes downloading.

/// Quick answer

Linearize restructures a PDF's internal object layout so a viewer can render the first page before the rest of the file has downloaded — commonly called 'Fast Web View'. The output's linearization is verified before it's returned, reported in pdf-info's own linearized field.
