ducativc1dec: try hard to produce a valid sequence layer header
Make sure the codec data in the sequence layer is always 4 bytes as per STRUCT_C
definition. Some files seem to come with larger, 0 padded, codec_data buffers...
Ensure that the Reserved6 bit of STRUCT_C is always set to 1 as the codec seems
to be strict about this and some files seem to have it set to 0...
