Tests require audeer >=1.21

Tests failing with audeer 1.20

>       dataset_cache = audeer.mkdir(tmpdir, 'cache')                                                                                                                                                                                                                                                                                                                         
E       TypeError: mkdir() takes 1 positional argument but 2 were given   

Errors fixed after running pip install audeer --upgrade that effectively installed 1.21
