Unify data/datasets folders into single folder / interface

[gautierdag]

I suggest unifying the data/datasets tasks into a single folder, along with some of the helper files (the relevant dataset/data ones) and the enums and samplers folder.

Does any other project share the same/similar datasets? Are they any plans to use it for other projects?
Without a use-case in the near future, I would question the value that this refactoring brings for now. We can still attempt it when a use-case comes up.

Sorry, I meant folder, not repo. Essentially bringing all data/dataset functions under one folder, then subdivided by actual dataset such as data/shapes .. etc . The idea is that we can then extend to a new dataset/task without much refactoring. And provide a single interface to import a specific dataset/task. What do you think?
