docs: A function that formats the progress information
  
      This function will be called periodically for each progress that is monitored.
      Overwrite this function in a subclass to implement a specific formating of the progress information
  
      :param count_value:      a number holding the current state
      :param max_count_value:  should be the largest number `count_value` can reach
      :param prepend:          additional text for each progress
      :param speed:            the speed estimation
      :param tet:              the total elapsed time
      :param ttg:              the time to go
      :param width:            the width for the progressbar, when set to `"auto"` this function
          should try to detect the width available
      :type width:             int or "auto"
