Fix address for gdrive download content

[swheaton]

There has previously been some tricks and attempts to confirm downloading large files from google drive without requiring user action. It seems that somewhat recently these stopped working.

Instead, if we fetch the file from drive.usercontent.google.com/download rather than drive.google.com/uc, we can bypass the confirm business.

Testing from within fiftyone because this module doesn't work on its own really.

import fiftyone as fo

# Set to new dir, or ensure quickstart-groups isn't downloaded yet
# fo.config.dataset_zoo_dir=''

fo.zoo.load_zoo_dataset('quickstart-groups')
