Dataframe converters incorrectly use positional access

    Description

      Both our dataframe-matrix and dataframe-frame converters assume positional access of the __INDEX column. This is incorrect as, for example, a serialization into json and subsequent deserialization loses this order (i.e., sorts by column name). This is a bug because our converters cannot even read data frames produced by SystemML in a previous script.
