Add a zip folder in the google drive address

[ioangatop]

Hi and thank you for releasing publicly the dataset!

Because the google drive has a limit of 50 files per about 40 minutes, its difficult to download the dataset from a python script. Thus, it would be great it all of the files where compressed as a zip file, so it will download only one file easy and fast with torchvision's download_and_extract_archive fucntion

thank you!
