https://huggingface.co/datasets/google/fleurs/commit/dcf80160cd77977490a8d32b370c027107f2407b 

real quick. 

I think the problem is that we cannot ensure that the metadata file is found before the audio. Or is this possible somehow @lhoestq ?

Status code:   400
Exception:     NotImplementedError
Message:       Extraction protocol for TAR archives like 'https://storage.googleapis.com/xtreme_translations/FLEURS/af_za.tar.gz' is not implemented in streaming mode. Please use `dl_manager.iter_archive` instead.
```

Am I the one who added this dataset ? Yes

Can I fix this somehow in the script? @lhoestq @severo
