Gah. One of the libraries I'm using just pushed out an API breaking change.

If you need a quick answer, follow the steps for installing OCRmyPDF in a development environment, and "pip install -r requirements.txt" to force it to use a compatible version of img2pdf.

I suspect many people will run into this so I did a quick release.

v3.2.1 should fix this issue
