Encode values immediately
...
This currently avoids buffering the collection, but not buffering them
individually where we still format it into a byte vector.
The main drive here is making the DirectoryEncoder less dependent on the
values. That is, it should be concerned with the Entry representation of
values only. A few decoders expect all values to strictly follow the
image directory and the data layout of such files should be controllable
by the user. This could be achieved by encoding dummy entries which are
later corrected once the actual item is known by seeking back and
writing the directory anew.
By no longer assuming values to be available on finishing a directory we
also prepare an interface that encodes an existing directory.

Allow non-chained directories in writer
...
This is just the implementation details. In the DirectoryEncoder we did
not differentiate between different directories that should go into the
main image chain and other directories. This is now possible by storing
the prior offset as an explicit Option<NonZeroU64>.
Additionally, the whole encoder did not allow any intermediate data
between its last directory and new directories on the chain. The offset
of the relevant `next` field was not stored explicitly but derived from
the current stream position at the moment of starting the directory.
This would not allow any padding data or data written outside the
returned `DirectoryEncoder` object.
This relaxed both requirements by turning the offsets into attributes.
