Added an io-stream-wrap variant of io-wrap that operates on streams. The strategy argument is applied to a tuple of streams: the input and the output stream.
Added an io-stream-wrap variant of io-wrap that operates on
streams. The strategy argument is applied to a tuple of streams: the
input and the output stream.

Reading aterms from a stream is easy (read-from-stream), so this kind
of wrap is useful for tools that are not aterm-to-aterm, but where one
of the inputs or outputs is an aterm.
