Make FMM python3 compatible

[fywu85]

Since python2 is officially out of support, can we move fmm from python2 to python3?

I have not tried it yet but you should be able to install the binding for python 3 as long as the correct python version is found.

Some modifications should be made to this file: https://github.com/cyang-kth/fmm/blob/master/python/CMakeLists.txt

When I try with python 3 installation on a separate environment created by anaconda, I encountered a problem of segment fault when calling from fmm import Network， the error needs further consideration.
