    soundfile objects.

- Add patch remove-contextlib2.patch:

- Disable python36 build because SciPy 1.6.0 dropped support for
  Python 3.6. Other packages from the NumPy family do the same
  (NEP29)
- Update requirements
- Enable tests. Use librosa-create-pooch-cache.py to provide the
  test data in librosa-pooch-cache.tar.gz. These files are under
  CC-BY-3.0 license.
