Increase chunk size for speeding up file downloads

Original fix: https://github.com/huggingface/huggingface_hub/pull/1267
Not sure this function is actually still called though.

I haven't done benches on this. Is there a dataset where files are hosted on the hub through cloudfront so we can have the same setup as in `hf_hub` ?

We simply do GET requests to hf.co to download files from the Hub right now. We may switch to hfh when we update how we do caching 

You can try on any dataset hosted on the hub like `imagenet-1k`
