I've implemented the ability to get the page corresponding to an entry in the outline (aka table of contents). This is admittedly quick and dirty. It works on the handful of PDF files I tried it with, but I haven't actively sought out corner cases.
This commit adds support for finding the next or previous pages in the document. This is especially useful when the page number isn't known, e.g. because it was reached via the outline.
I didn't realize I already had a handy reference to *pdf.Reader present in Outline (by way of Value). This means Page() can be a method of Outline, rather than a method of *pdf.Reader, which seems to me a more logical place for it. Best to change this now, before anyone else might be using this code.

in the outline (aka table of contents), and to walk to the next or previous
page in the document given just a Page object.
