To improve usability it is now possible to directly pass paths or match patterns
as arguments to pxar extract to partially restore an archive.
The patterns provided via CLI are appended to the ones read from file by the
--files-from option in order to have priority over those.

Allows to partially restore an archive by passing match patterns to the restore
function.
The whole restore is performed in sequential, therefore the whole archive has to
be read.
By wrapping the RawFd into an Option it can be controlled if the corresponding
part is restored (in case of Some(fd)) or if the Reader reads over it
without restore (in case of None).

match_exclude_pattern() does not need a '&mut self' reference to the encoder,
move it therefore out of the impl.
Further, this patch contains some naming and formatting cosmetics.

dir_count was used to track the number of directory entries to store in the
archive and bail if the maximum is exceeded.
As the number of entries is equally obtained from the list of the filenames to
include, use that one instead.

Partial matches make only sense for directories, files are always leafs of the
tree. Take this into account in order to avoid restoring of files which only
matched the front of a match pattern.

In order to improve usablity, the target on archive extraction will be the
current working directory by default.
A different target can be provided via the optional --target <PATH> parameter.

This splits the functionality of restore_sequential() into several smaller
functions in order to allow to reuse them when restoring by seeking based on
the goodbye table offsets.

Commit cd7dc87903 introduced the special treatment
for .pxarexclude files when stored in the archive.
The incorrect placement of a code snipplet from this path leads to an incorrect
offset and size stored in the goodbye table.
This fix places the start to the correct position, restoring the previously
correct behaviour.

We can now use iter::from_fn() which makes for a much nicer
logic. The only thing better is going to be when we can use
generators with `yield`.
