This change allows the from_config factory function to better support two angles from which it will most commonly be used. 1. When SDK is being used from within OSC, OSC will have obtained configuration data from OCC and is better served by passing it directly into SDK rather than SDK additionally accessing that data. 2. Direct users of the SDK, such as customer applications, are less likely to have dealt directly with OCC and are better served by just passing in the name of the configuration they want to run with.
