.SYNOPSIS
    Automates ryzenAdj calls based on custom conditions
.DESCRIPTION
    This script is designed to provide maximum flexibility to the user. For that reason it does not use parameters.
    Instead of parameters, you need to populate the functions in the configuration section with your custom adjustments and additional custom code.
