mxfdec: Ignore the last entry in Avid's index table segments
...
The last entry is the total size of the essence container.
Previously a TemporalOffset error would be logged, even though segments like
these are expected.

mxfdec: Hybrid demuxing/seeking solution
...
This uses the old demuxing code for OP1a and separate demuxing code for OPAtom.
Timestamp output is added to the old demuxing code.
The seeking code is made to seek to the start of the desired EditUnit only,
from which the normal demuxing code takes over (if OP1a). This means we don't
use delta entries or slices, only StreamOffsets.
OPAtom seeking basically works like before.
This also makes D-10 seeking behave the same way as OP1a and OPAtom. In other
words, we allow seeking before the start or past the end for D-10 too.
This fixes ticket #746 .

mxfdec: Speed up metadata and index parsing
...
Specifically, this means parsing as before until we run into essence.
At that point we seek to the footer and parse until EOF. After that we start
seeking backward to the previous partition and parse that until we run into
essence or the next partition. This procedure is repeated until we encounter
the last partition we parsed in the forward direction.
The end result of all this is that large essence containers aren't needlessly
parsed. This speeds up parsing large files a lot.
