Handle Marcxml documents as returned by ZOOM

The ZOOM API returns Marcxml records as documents rather than as
part of a larger document, and explicitly declares the namespace on the
record element. With the changes in this patch, MarcxmlReader can be
hooked straight to the streamed output of a ZOOM query.
Add object mode for MiJ writer

In cases where MiJ records are needed for further processing,
stringifying the results of the formatting merely adds unnecessary
overhead, so this patch adds an object mode to the MiJ writer.
