DepreciationWarning and new release

[MoiseRousseau]

I installed PRIMME Python interface from this repo:

git clone https://github.com/primme/primme
cd primme
make
cd Python
pip install .

However, when running example.py, I got into the warning:

DeprecationWarning: Please use `aslinearoperator` from the `scipy.sparse.linalg` namespace, the `scipy.sparse.linalg.interface` namespace is deprecated.

To fix it, changing the scipy.sparse.linalg.interface to scipy.sparse.linalg in primme.c and primme.pyx fixes the problem, something such as:

sed -i 's/scipy\.sparse\.linalg\.interface/scipy\.sparse\.linalg/g' primme.c primme.pyx

Can you fix the problem on the repo ? Also, can you create a new release on GitHub with the latest development ?
