[WINESYNC] msi: Add support for exporting binary streams (Binary/Icon tables).

The Binary and Icon tables store their data in a different format from
    other tables, one column of the data is stored as a "stream" instead
    of a normal text field.  With this patch those tables can now be
    exported properly by the MSI export functionality.
