get returns a variety of data structs
 
    This method provides a variety of selectors to return info, feedback,
    or gain data in a variety of formats. It always returns immediately
    and may return the same data more than once. In practice you should
    use an appropriate convenience wrapper.

    If a struct returns empty or full of NaN, make sure that the
    appropriate polling rate has been set.
 
    Example
       % Request info/gains at 5Hz and feedback at 100Hz
       HebiLookup.setLookupFrequency(5);
       group.setFeedbackFrequency(100);
 
    DataType argument
       'Info'         returns meta information about the module, such
                      as versions, addresses, names, etc.
       'Gains'        returns the gains for the active control strategy.
                      Gains that are disabled, are set to NaN.
       'SafetyParams' returns safety parameters such as limits
       'Feedback'     returns aggregated sensor feedback
 
    'View' Parameter ('Feedback' only)
       'Simple'   returns basic feedback. This is appropriate for most
                  users. (default)
       'Full'     returns all available feedback. This is appropriate
                  for advanced users that care about additional
                  timestamps and less common sensors.
       'IO'       returns feedback fields specific to I/O devices,
                  such as analog and digital pins, or the button and
                  slider states of the HEBI Mobile I/O app.
       'Mobile'   returns feedback fields specific to mobile devices,
                  such as GPS and ARKit/ARCore estimates.
