docs: Ensure that all constant streams referenced in the sensor graph have a value.
  
          Constant streams that are automatically created by the compiler are initialized
          as part of the compilation process but it's possible that the user references
          other constant streams but never assigns them an explicit initial value.  This
          function will initialize them all to a default value (0 if not passed) and
          return the streams that were so initialized.
  
          Args:
              value (int): Optional value to use to initialize all uninitialized constants.
                  Defaults to 0 if not passed.
  
          Returns:
              list(DataStream): A list of all of the constant streams that were not previously
                  initialized and were initialized to the given value in this function.
