Fix the sideways scan

Scanners and phone cameras love producing sideways PDFs, and most viewers only rotate the view, not the file. Rotate the actual pages so the document opens the right way up for everyone you send it to.

• ✓90° either direction or a full 180° flip
• ✓Rotation is saved into the file, not just the viewer
• ✓Combine with merge to fix and combine scans in one session
