lavf/mxfdec: support segmented frame layout as separate fields layout

Browse Source 
According to S377M, segmented frame layout is identical to separate
field layout except that the two fields are taken from a single scan
of the incoming image, ie: they are coincident in time. Thus the
resulting frame is progressive.
