[MAINT] Favor pathlib over path string manipulation

[fabianegli]

It would be better to not manually work with path strings but use the modern pathlib instead.

sdrf-pipelines/sdrf_pipelines/parse_sdrf.py

Line 124 in 837af51

Path = os.path.split(sdrf_file)[0] + '/'

Note that Path is orange in the above code snippet? That's because it is the name of the Path object in the Python builtin pathlib library and considered an internal variable. If possible these names should not be used for custom variables if not for a very good reason.
