v0.4.7

A significant number of changes.
Change how all the mixer configuration is done. There were too many 'special cases' in the code. This is now done in the configuration. This allows for more flexibility in mapping values as well.
Code should now be more maintainable.
Applied Black code formatting
Added more test code
