Fix incorrect extraction of Origin

Browse Source 
The code that attempted to extract origin (4B.02) was put in the wrong
metadata handler and was also read as the wrong integer type. According
ST 377-1 Origin is of type "Position" (Int64) in the Timeline Track, not
a 8 bit unsigned integer in the Sequence.
