Hot linking to a UCI dataset

[justinormont]

I noticed we are hot linking to a UCI dataset:

machinelearning/build.proj

Line 80 in a6e3c0a

Url="https://archive.ics.uci.edu/ml/machine-learning-databases/wine-quality/winequality-white.csv"

We should get CELA approval for hot linking, and if possible get approval to redistribute the full dataset in either the /test/data/ folder (if small), or the CDN (if large).

We should still explore Git LFS for hosting datasets. [relevant discussion]
