Title: WIP: Refactor enet_coordinate_descent

This PR aims to simplify ``cd_fast.enet_coordinate_descent`` by transfering most of the code to Python so that only the inner loop of the coordinate descent iterations remains in Cython. This PR is closely connected to #992.

The same has been done by @fabianp here:

Pleas don't bother with checking docstrings and similar yet.
I first want do some benchmarking before making things pretty.
