Adding a tesseract with additional languages for CentOS

[DigitLib]

This PR install tesseract and an additional laguage-packs in CentOS.

@DigitLib, do you have any images we can test the language packs on to make sure they work correctly?

[seth-shaw-unlv]

Would you also add the libraries to the Debian.yml so we can just do them both in a single PR?

__crayfish_packages:
  - imagemagick
  - tesseract-ocr
  - tesseract-ocr-fra
  - tesseract-ocr-deu
  - tesseract-ocr-ita
  - tesseract-ocr-spa
  - tesseract-ocr-srp

@seth-shaw-unlv sorry for the late answer (time-zones).
Debian: Good idea to make equal installations on both distros.
Here is two images tiff and jpg on Serbian https://digitalna.milutinbojic.org.rs/files/claw-test-files/test-files-claw.zip hope that it will be OK for testing, I tested it on Islandora 7 and was OK if you need a short pdf I can send it also...

@DigitLib, the CentOS works fine for me. Just add the Debian.yml changes to the PR so I can test it in Ubuntu and we will be good to go.

@seth-shaw-unlv Excellent!! 👍

[seth-shaw-unlv]

I just updated the Debian.yml with the packages. This replaces PR 10.

[seth-shaw-unlv]

Good to go.
