Setup script tar problem

[msallese31]

When running sh ./setup/setup.sh, I get the following error:

sallese@sallese-To-be-filled-by-O-E-M:~/dog-breeds-classification$ ./setup/setup.sh

It seems to think that the tar file isn't in gzip format. Putting together a PR for what fixes this for me. I'm not sure if others have hit this so if that doesn't make sense to merge, that's ok.

I don't have permissions to push to a branch. If others hit this problem, I had to modify setup/download_stanford_dogs_dataset.sh with the following changes:

diff --git a/setup/download_stanford_dogs_dataset.sh b/setup/download_stanford_dogs_dataset.sh

Just taking out the z in the tar xfz in the setup/download_stanford_dogs_dataset.sh
