process signal_data with data_type v4c.DATA_TYPE_SIGNED_INTEL and v4c.DATA_TYPE_SIGNED_MOTOROLA

[heavy-matill]

After upgrading to INCA V7.2 I get .mf4-files that contain data of type signed intel. Adding those lines fixes the problem and I can import the measurement.

The following was the error log

MdfException                              Traceback (most recent call last)
