Proxy issue for upstream issues in peekpdf & libqpdf #97
Description
We currently require peekpdf<=9.5 in the xtpdf unit because of the following issues:
- Regression from 9.2.1 (unable to find any pages while recovering damaged file) pikepdf/pikepdf#674
- libqpdf refuses to parse malicious document (unable to find any pages while recovering damaged file) qpdf/qpdf#1552
We have multiple ways to resolve this issue, depending on the outcome. If the current behavior is intended, we can either keep the version requirement or re-introduce a dependency on pypdf2 and fall back to that one on error.
