cuCIM backend not fully supported

After changes introduced in https://github.com/DIAGNijmegen/pathology-whole-slide-data/pull/56 by @siemdejong that fixed https://github.com/DIAGNijmegen/pathology-whole-slide-data/issues/55, new errors occur therefore it seems that the cuCIM backend is not yet fully supported.

After introducing quick fix - casting PosixPath to str in wholeslidedata/interoperability/cucim/backend.py it works
