Increase the proportion of hf.co datasets that can be previewed
For different reasons, some datasets cannot be previewed. It might be because the loading script is buggy, because the data is in a format that cannot be streamed, etc.

The script https://github.com/huggingface/datasets-preview-backend/blob/master/quality/test_datasets.py tests the three endpoints on all the datasets in hf.co and outputs a data file that can be analysed in https://observablehq.com/@huggingface/quality-assessment-of-datasets-loading.

The goal is to understand which problems arise most and try to fix the ones that can be addressed (here or in [datasets](https://github.com/huggingface/datasets/)) so that the largest part of the hf.co datasets can be previewed.
