Download from data.europa.eu fails due to complex "name" metadata

[alvarolopez]

In some cases, downloading data from data.europa.eu (implemented in #86) is broken, due to the internationalization of the file name. In those cases, datahugger fails with Error: argument should be a str or an os.PathLike object where __fspath__ returns a str, not 'list.

For instance, when downloading https://data.europa.eu/data/datasets/cordish2020projects the file info looks as follows:
