Add pypi 10k packages with most dependents dataset (#711)

From manual inspection, this dataset generated through the [libraries.io
API](https://libraries.io/api#project-search) seems more mainstream than
the current 8k one, which is also preserved. I've added the dataset to
the repo because the API requires an API key.
