fit_to_roi not applied

[martinschorb]

Hi @constantinpape ,

I tried to implement what you suggested here #42 (comment) in mobie-utils-pythonbut found thatfit_to_roiseems to be ignored bycopy_volume`. The resulting file still has full dimensions.

That's why this fails. https://github.com/mobie/mobie-utils-python/blob/8848c64af5c717af31b396d75b501256ee3d768a/test/test_image_data.py#L372

Here's the config that has the correct parameter.
global.config
