Verbose controls functionality (don't think it should)
This line:
https://git.gfz-potsdam.de/danschef/arosics/-/blob/main/arosics/CoReg.py#L444
is performing a write_shapefile or something similar ONLY if verbose is set. So, as by default it's off I never saw this issue and as I'm using non-standard planetary projections, I cannot use all the things that arosics offers. But I was very surprised when a working pipeline broke, just because I switched on "verbose=True" at the beginning.
I haven't checked if this happens more than once, but IMHO, functional code should not depend on a setting that is usually used for deciding how much feedback is given on everything.
