The blks.channel_model block would be more useful to GRC if it had some
callbacks (functions to set the input parameters at runtime). So, for
example, one could vary the noise voltage while the flow graph is running.
I attached a diff with 3 callbacks added. Hopefully, it will make its
way into blks2.
