Package with libpaper

[rrthomas]

It would be nice if users didn't have to install libpaper separately (see #69).

Packaging with pip seems possible, with https://github.com/pypa/cibuildwheel/

But this doesn't give much help for building and installing libpaper—it's more aimed at building Python extensions.

An alternative would be to package libpaper and PSUtils for Conda, but that would only help Conda users.

Drive-by comment, without much thought behind it... but would the port to PyMuPDF perhaps make libpaper redundant? See pymupdf.paper_sizes() and pymupdf.paper_size().

Good idea, but MuPDF doesn't seem to have any sort of configurability: looking at the source it just has a small number of hard-wired paper sizes. Given that Ghostscript itself can use libpaper, it would make sense if MuPDF could too; but that's not a PSUtils issue!
