Dear Maintainer,
On a PDF file generated by inkscape, pdfposter fails with this error:

---- processing page 1 -----
Deciding for 3 columns and 2 rows of portrait pages.

TypeError: a bytes-like object is required, not 'str'
I tried removing and re-installing the package, with no effect.
Google AI suggests:
The error a bytes-like object is required in pdfposter typically
occurs because of a conflict between Python 2 and Python 3 or an
outdated dependency. The issue arises because Python 3 strictly
distinguishes between strings (Unicode text) and bytes (binary data),
while Python 2 did not. 
Solution 1: Use an updated version
The most direct cause of this error is using an old version of
pdfposter that was built for Python 2. Versions 0.7 and earlier did
not support Python 3 and used an outdated library (pyPdf). A fix was
implemented in version 0.8 to make it Python 3 compatible by switching
to PyPDF2.
I see there have been several new versions released this summer.
Pdfposter version 0.9 included a port to version 3 of the pypdf
library, so I expect just packaging a current version would fix the
problem.
