Adapt to the decoder/accessor method changes introduced in the pxar
library, which were introduced in order to move the consistency check
for metadata and payload data archives.
The new location of the checks allows to access the pxar archive via
a `Split` variant reader instance, without penalization when just
accessing the metadata, not reading any payload data.
This greatly improves performance when accessing fuse mounted
archives.

Allow to pass an optional input path to mount a split pxar archive
with dedicated payload data file.

... 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.

besides harmonizing versions, the only global change is that the tokio-io
feature of pxar is now implied since its default anyway, instead of being
spelled out.

pbs-buildcfg is the only one that needs to inherit the version as well, since
it stores it in the compiled crate.

it's used by pxar-bin and proxmox-backup-client for
mounting, but pbs-client is used by more (eg. the
proxmox-backup-qemu library which really doesn't need to
pull in any fuse dependencies)
