Add Medical Decathlon Datasets

I am new to Julia and I am working on a medical imaging research project. I would like to add the medical decathlon datasets (http://medicaldecathlon.com) (https://arxiv.org/pdf/1902.09063.pdf) to this repo as I think it would be a great way for me to learn what's going on and it would likely benefit the entire Julia community. I will definitely need help in this endeavor though so please let me know if that is something of interest to the contributors of this project.
