Downloading IXI dataset: link broken

[jeandut]

When running the download script in the IXI folder I now get:
python download.py --output-folder ./IXI

@AyedSamy and @sssilvar could you take a look when you have time ?

Seeing this file it looks like IXI Tiny can be found there: https://www.dropbox.com/s/ogxjwjxdv5mieah/ixi_tiny.zip?dl=1

However simply changing the URL creates this new error when using benchmarking:
Traceback (most recent call last):

Quoting @sharkovsky:

I just ran into the same problem!

It has to do with Mendeley archive's hosting, but I do not know any more details.

The new link (working for me) seems to be https://prod-dcd-datasets-cache-zipfiles.s3.eu-west-1.amazonaws.com/7kd5wj7v7p-3.zip

Should be solved now in #257 again thank you both for the help.
