`_get_response_from_http` doesn't work on Colab.

🐛 Describe the bug

Code ponter here: https://github.com/pytorch/data/blob/6c5a9cb040740db1c5385fe9cc6ca3e5307d49f0/torchdata/datapipes/iter/load/online.py#L13

Faling code:

import requests
with requests.Session() as session:
    r = session.get(url, stream=True)
    print(r.raw.read())

Code with right result:

import requests
with requests.Session() as session:
    r = session.get(url, stream=True)
    print(r.text)

Versions

And, the reason it happens on Colab is:

google-colab 1.0.0 requires requests~=2.23.0, but you have requests 2.27.1 which is incompatible.

Found the culprit. We rely on requests to provide correct HTTPResponse and requests is relying on urllib3 to decompress the content within HTTPResponse. But, for urllib3 1.24, __iter__ within HTTPRespnse was not implemented.

I will open a PR to set urllib3 >= 1.25
