Store all partitions & primer packs in memory for faster access.
This is later needed for fast seeking.
Pre-fill the list of partitions with the content of the random
index pack.
Don't parse metadata of an partition twice.
Store the MXF metadata in a hash table, keyed by the
instance UID. This simplifies resolval of the metadata
and makes looping over all metadata sets unnecessary
in most cases.
Additionally parse metadata always. If we already have
a metadata set with the same UID replace it only if
the new metadata set is from a later offset. This
fixes metadata parsing of files where following partitions
don't have a complete copy of the previous metadata.

Implement support for OP2a/b/c and OP3a/b/c, i.e. tracks with
more than a single component. This currently only works for
the case where the components are stored in playback order
in the file.
Set some more default/distinguished values for the structural
metadata.
Make some types more strict by choosing the correct subclasses.
Set DISCONT flag on buffers after a component switch.
Take the last partition from the random index pack for the footer
partition of the header partition doesn't reference the footer
partition. This gives us the final structural metadata for
some more files in the beginning.

Fix height calculation from the frame layout a bit more and
add a TODO to check if it's really correct now or if it needs
more fixing (especially, does the framerate need adjustments?).

Remove the concept of "final" metadata, broken files have updated
metadata in following partitions even if the current partition
is closed and complete.
If there's a second primer pack inside a partition ignore the second
one instead of throwing an error.
Store the type of a track (audio, video, timestamp, ...) inside the
track struct.
Post no-more-pads only once for a stream and not a second time
when switching the currently playing package.
When updating all streams make sure that we could select and find
a package instead of dereferencing NULL.
Allow descriptive metadata inside metadata parts of a file when
pulling the footer metadata too.
Only switch the currently playing package if a new one was chosen
and the metadata is in a resolved state. If the latter isn't true
postpone the switch until the metadata is resolved.
Pull the footer metadata directly after parsing the header partition
pack if it's not closed or not complete instead of waiting until
the next KLV packet.
