permission denied when working with temporary file

[sygout]

the following code creates a problem on Windows:

´´´
with tempfile.NamedTemporaryFile(suffix=".owl") as handle:
super().save(file=handle.name, format="rdfxml", **kwargs)
graph = rdflib.Graph()
graph.parse(handle.name, format="xml")
graph.serialize(destination=filename, format=format)
´´´

It is related to an issue with tempfile library. See for example discussion: https://stackoverflow.com/questions/23212435/permission-denied-to-write-to-my-temporary-file

Similar issue might be present every time ontopy tries to work with tempfile.

The nice thing with the with tempfile.NamedTemporaryFile(suffix=".owl") as handle: clause is that it deletes the temporary file when leaving it. Won't adding the argument mode="w" to tempfile.NamedTemporaryFile solve the issue?
