FeedbackStruct shows feedback coming from groups of modules.
 
    Feedback structs are instantiated by various API calls and can't be
    instantiated directly by users. Depending on the requested
    feedback, the returned struct may provide a different 'view' on the
    data, i.e., return a specific subset of sensor feedback and states.
 
    A list of currently available views and their fields is below. You can
    find more detailed information about feedback fields at docs.hebi.us.
