Similar to gst_harness_add_src, this allows you to send the data coming out
of your harnessed #GstElement to a sink-element, allowing to test different
responses the element output might create in sink elements. An example might
be an existing sink providing some analytical data on the input it receives that
can be useful to your testing. If the goal is to test a sink-element itself,
this is better achieved using gst_harness_new directly on the sink.
If a sink-harness already exists it will be replaced.
