First release of Pooch :tada:

Pooch will manage downloading your sample data files over HTTP from a server and storing them in a local directory:

* Download a file only if it's not in the local storage.
* Check the SHA256 hash to make sure the file is not corrupted or needs updating.
* If the hash is different from the registry, Pooch will download a new version of the file.
* If the hash still doesn't match, Pooch will raise an exception warning of possible data corruption.
