py-pspdfutils: update to 3.2.0.

This release improves support for reading the paper size of PostScript
files. In particular, it will try to use PageBoundingBox, BoundingBox, and
HiResBoundingBox settings, if there is no DocumentMedia, in that order. If
it uses a BoundingBox or HiResBoundingBox setting, it will warn the user
that it has guessed the page size when this matters (for example, when
running psnup).
