HANS dataset preview broken
Hi! I've opened a PR that should make this dataset stremable. You can test it as follows:
```python
from datasets import load_dataset
dset = load_dataset("hans", split="train", streaming=True, revision="49decd29839c792ecc24ac88f861cbdec30c1c40")
```

@severo The current script doesn't throw an error in normal mode (only in streaming mode) on my local machine or in Colab. Can you update your installation of `datasets` and see if that fixes the issue?

HANS dataset preview is broken with error 400

Am I the one who added this dataset ? No
