Core dump in ocrd-cis-ocropy-denoise

[stefanCCS]

With an update of ocrd_all from 22.03.22 I get this core dump:

ocrd-cis-ocropy-denoise -I OCR-D-BIN-REG -O OCR-D-BIN-REG-DENOISE -P level-of-operation region
08:45:41.815 INFO processor.OcropyDenoise - INPUT FILE 0 / P_4074_007817778_00001

Segmentation fault (core dumped)

Maybe this is related to #89

Thanks @stefanCCS, that clue led me in the right direction. Yes, same cause as #89.

It's a bug in OpenCV, which has been fixed upstream, but no release yet.

Can you please try again with the most recent version of #87?
