EOL character on Windows

[TheSidi]

Hi,

I had some issues with the EOL character in the "fdmfile.txt" and the input file when running pyFDMNES on a Windows machine. It seems that only a \n instead of a \n\r is written as an EOL which prevents FDMNES from running on Windows.

Following the suggestion from here:
https://stackoverflow.com/questions/38074811/what-is-os-linesep-for

I changed open(path, "w") to open(path, "wb") in line 667 and 694 of pyFDMNES.py

That seems to do the job for me.
