Standalone Python Library only using one core

[MrMarlin]

Hi at all

Firstly thank you for developing and maintaining such a great project. I am really enjoying it. My issue is, that although I set the CPU_cores_to_use argument to 8 the script is still using only one core. It also logs using single-core only.

Is there a setting I am missing or what would be the steps to enable the script to use more than one core?

Thanks and have a nice one
