Convert ABBYY OCR file format to ALTO #220

Closed ponchofiesta closed 5 years ago

As Kitodo.Presentation doesn't support the old ABBYY Finereader OCR file format, we need an action to convert these files.

This adds the IOcrConverter interface and an AbbyyToAltoOcrConverter implementation using the converter package from https://github.com/Mewel/abbyy-to-alto. The Maven repo described there didn't work for me. So I forked it to our namespace and used Jitpack.io to get a package out of the Git repo.

The converter checks the source file format with a simple check ("<alto "=ALTO format, "<document "=Finereader format). It skips files in correct format and drops files in unsupported formats.

You can add this action to the importer like this:

importer:
  actionsBeforeIndexing:
    - abbyyToAltoOcrConvertAction
   # Maybe followed by actions using these ALTO files.
    - addFullPdfToMetsAction
    - preproduceFullPdfFileConvertAction
