Polyphase Channelizer Viewer is fully functional again, now using the

TestTuner and TestTunerController implementations.  This implementation
only has support for channels that are completely centered within a
channelizer output.  Two output slice stitching to form a composite
channel will be implemented next.

Initial profiling indicates that the FFT function within the polyphase
channelizer is now the dominant processing workload - 28% cpu loading
when channelizing a 10 MHz sample rate input into 800 channels running
at 25.0 kHz each.  This is ideal for offloading to an OpenCL kernel and
running on a GPU.
