mxfdec: Add support for Avid indexes
...
These indexes duplicate every entry and have the total size of the essence
container as the last entry.
This patch also computes the size of the packets when unknown.

mxfdec: Bring back accumulated_offset that was removed in 5e67e3e

I thought it had to do with file offsets, but's actually the offset inside
the essence container.
In other words, unbreak multiple EditUnitByteCounts.

It is a really bad idea to assign a video codec id

mxfdec: Parse more values in PartitionPack

These values include KAGSize, HeaderByteCount and IndexByteCount.
The length of the pack itself is also stored, and KAGSize is sanity checked.
The FATE sample has KAGSize == 0, which is adjusted to 512.
Other bad KAGSizes are set to 1.

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.

Manual replacements are done in this commit.
In many cases, the id is some constant made up number (e.g. 0 for video
and 1 for audio), which is then not used in the demuxer for anything.
Those ids are removed.
