Unsupported image format #3905
Description
3.18.2 has difficulties with PDFs with unsupported image formats when we try to get a PIL image out of a pikepdf Image.
Some research suggests this might be related to the DecodeParams used by pikepdf (see pikepdf/pikepdf#423).
Some related stacktraces suggest breakage in pikepdf even before the point of converting to a PIL Image and for those cases it seems like pikepdf 7.0.0 has a fix which works:
Fixed an issue with extracting images that were compressed with multiple compression filters that also had custom decode parameters.
