invalid TIFF tags in GT

[bertsky]

Again, a report on GT issues (not assets):

In ...

• estor_rechtsgelehrsamkeit02_1758,
• praetorius_verrichtung_1668 and
• justi_abhandlung01_1758

...images have badly formatted tags, which cause ImageMagick to issue warnings:

See OCR-D/ocrd_olena#4 – this subsequently causes OLENA binarization to to fail with segfault!

Of course, our components should be robust against such problems. But given that OLENA is not maintained and OCR-D module projects are in the middle of final sprint, and you are going to re-publish GT bags anyway because of the other issues: Can you please fix this in the GT repo now?

Closing because solved for OLENA via OCR-D/ocrd_olena#6.
