Multi Language OCR - Docker mod for papermerge

This mod adds multi language OCR packages to papermerge, to be installed/updated during container start.

In papermerge docker arguments, set an environment variable DOCKER_MODS=linuxserver/mods:papermerge-multilangocr to enable this mod.

If adding multiple mods, enter them in an array separated by |, such as DOCKER_MODS=linuxserver/mods:papermerge-multilangocr|linuxserver/mods:papermerge-mod2

Then set an environment variable named OCRLANG and set it to the language codes that follow tesseract-ocr- from this page. You can add multiple codes that are comma separated, with no spaces.

For example, if you want to enable OCR for Chinese Simple and Belarusian, you'd set the var as -e OCRLANG="chi-sim,bel".
