Multiprocessing issue

Hello Daniel! Thanks for the Arosics package I just started using it for my remote sensing projects and happened to run into a problem recently when wanting to coregister two arrays using Geoarray after defining the projection system as explained in this part of the documentation (https://danschef.git-pages.gfz-potsdam.de/arosics/doc/usage/local_coreg.html#detect-and-correct-local-shifts-without-any-disk-access) I'm trying to run a local coregistration using arosics version : 1.4.6
