Extension: Rename Images to fit GT-File by name

[M3ssman]

Description

Actually, when images files ere referenced in mets.xml in group , the get downloaded an pushed to directory.
This way, the naming similarity between image and GT-data is lost. But this similarity is a key requirement for tools like Transkribus or LAREX to match image with GT-data for further corrections or extensions.

Even worse, because our data consists of a overall sample of 40.000+ prints, it includes for example several images named "00000008.jpg" which could overwrite each other.

Proposal: each image file is linked to a physical page.
This container has an attribute CONTENTIDS which holds the requested image URN which corresponds the OCR-data URN with all :-characters being replaced by + and a final underscore with the language ISO-code attached.

[M3ssman]

For a test sample cf https://github.com/M3ssman/gt-test/releases/tag/v2.1.2 , where for 128 GT-Pages (Latin) only 108 images got included, since 20 images collide.

The problem is solved with the update of ocr-d (Bagit). Also use the new action workflow.

Re-open, some more review required.

IIUC this behavior should be fixed since v2.59.0, the relevant PR is OCR-D/core#1137.

Is there a regression, are you still experiencing files being overwritten when bagging?

@kba I'll take a closer look at the relevant modifications and try this out with our custom setup ASAP
