`pip install fastFM` does not resolve dependencies on macOS

[chezou]

Before installing Cython, pip install fastFM fails. This should be resolved automatically.

(venv) ~/w/ml-at-work (venv) pip install fastFM                                                                                                                          21:59:12

After installing Cython and numpy manually, it is able to install via pip.

Thanks for the report. Can you add 'cython' here https://github.com/ibayer/fastFM/blob/master/setup.py#L63 and try again? Travis-ci seems to resolve the dependencies properly on OSX.

@ibayer I made a PR on #115 Could you have a look it?
