[Feature Request]: Add Even Number Spread View and Toggle Between Odd/Even

Feature Description

When using double-page view, Stirling currently only shows an odd-numbered view, i.e. the left-hand page is odd : 1-2, 3-4, etc. For documents with a single title page, it is essential to be able to view even spreads after a single cover page : 1, 2-3, 4-5, etc. This feature exists in Acrobat as well as Firefox's built-in PDF viewer.

Why is this feature valuable?

Architecture firms (in my case) often send tender documents as PDFs with both a single title page and multiple spread pages. These are difficult to preview in a viewer without the ability to switch between odd/even spreads.

Suggested Implementation

The feature could be a toggle that appears when double-page view is selected, with one or the other selected by default (the current setting, odd, being more common I imagine).
