Pxar archives with format version 2 allows to store optional
information file format version and prelude entries.
Cover the case for these entries, the file format version entry being
introduced to distinguish between different file formats used for
encoding as well as the prelude entry used to store optional metadata
such as the pxar cli exlude parameters.
Add the logic to accept and decode these prelude entries when
accessing the archive via a decoder instance.
For now simply ignore them.

... and adapt to the new reader/writer variant for encoder or
decoder/accessor to attach a dedicated payload input/output for split
pxar archives.
In preparation for look-ahead caching, where a passing around of
per-directory level encoder instances with internal references is
not feasible.
Previously, for each directory level a new encoder instance has been
generated, restricting possible implementation errors. These encoder
instances have been internally linked by references to keep track of
the state changes in a parent child relationship.
This is however not feasible when the encoder has to be passed by
mutable reference, as required by the look-ahead cache
implementation. The encoder has therefore been adapted to use a
single instance implementation with an internal stack keeping track
of the state.
Depends on the bumped pxar library version, including the patches to
attach the corresponding variant for the pxar reader/writer
instantiation.

the snapshot string format is not backwards compatible since it now has
an in-line namespace prefix. it's possible to select which magic to use
at the start of the backup, since a tape backup job knows whether it
operates on non-root namespaces up-front.
the MediaCatalog itself also has a similar incompatible change, but
there
- updating existing catalogs in-place
- not knowing what the catalog will contain in the future when initially
creating/opening it
makes bumping the magic there harder. since the tape contents are
sufficiently guarded by the other two bumps, ignoring the
backwards-incomaptible change of the on-disk catalogs seems like an okay
tradeoff.

both used the 'Display' trait of pbs_datastore::BackupDir, which is not
intended to be serialized anywhere. Instead, manually format the path
using the print_ns_and_snapshot helper, and conversely, parse with
'parse_ns_and_snapshot'. to be a bit safer, change the register_snapshot
signature to take a BackupNamespace and BackupDir instead of a string.

- use hex crate to generate/parse hex digest
