change sklearn to scikit-learn

[lacava]

pypi doesn't accept sklearn as a dependency anymore; has to be scikit-learn

ffx/setup.py

Line 18 in ced56d9

install_requires=['click>=5.0', 'contextlib2>=0.5.4', 'numpy', 'pandas', 'six', 'sklearn',],

Unfortunately I don't have permission to commit the fix directly. I do have permission to make a new release (at least, a few years ago I did!) but need to have that fix committed first. @natekupp are you active in GitHub these days?

As a workaround, this works:

$ SKLEARN_ALLOW_DEPRECATED_SKLEARN_PACKAGE_INSTALL=True pip install ffx
