[SciPy-Dev] New subpackage: scipy.data

[Hameer Abbasi]

I concur with Stefan. Not having datasets in a package seems like the best
way to go. There should be a separate go-to place for datasets (other than
minimal ones for test cases).

I would recommend branching off all datasets... Otherwise we add to Scipy's
already significant size.

As a steps towards the deprecation of `misc`, I propose that we create a
new package, `scipy.data`, for holding data sets. `ascent()` and `face()`
would move there, and the new ECG data set proposed in a current pull
request (https://github.com/scipy/scipy/pull/8627) would be put there.


We've been doing this in scikit-image for a long time, and now regret
having any binary data in the repository; we are working on a way of
hosting it outside instead.

Can we standardize on downloader tools? There are examples in
scikit-learn, dipy, and many other packages. We were thinking of a very
lightweight spec + tools for solving this problem a while ago, but never
got very far:
