Re-include metadata analysis tools
Originally created by @huertanix on #17178 (Redmine)
It appears that pdf-redact-tools was removed in #15291 (closed). Although this and other tools used for metadata analysis can be installed on Tails with an internet-connected computer, there’s some particularities with SecureDrop’s airgap requirement that make the addition of new software much more challenging and largely impractical. It would be great to have the tools mentioned in Freedom of the Press Foundation’s guide on metadata (https://freedom.press/training/everything-you-wanted-know-about-media-metadata-were-afraid-ask/) installed by default. This would include:
- pdf-redact-tools
- tesseract-ocr
- ffmpeg
