parallel prediction not working on Windows

[mhellstr]

If I use the ASE interface on Windows I get the below error. It works fine if I comment out the line with prepare_parallel() in SGDMLCalculator (such that I run in serial?). Would it be possible to check for the OS and run sgdml-via-ase in serial on Windows?

The above exception was the direct cause of the following exception:
