NYU HDF5 Dataset Download

For anyone who cannot open the `http://datasets.lids.mit.edu/sparse-to-dense/data/nyudepthv2.tar.gz` webpage with Chrome, or cannot use `wget http://datasets.lids.mit.edu/sparse-to-dense/data/nyudepthv2.tar.gz` to download it in terminal.

I found using `wget --no-check-certificate http://datasets.lids.mit.edu/sparse-to-dense/data/nyudepthv2.tar.gz` in terminal works. Firefox can also open the webpage. I guess this is because the website uses `http`, instead of `https`.
