ChannelSpectrumConfig message subsumes FIFONotify.
...
Separate channel spectrum config from spectrum data. This will permit sending config info only when necessary.
Use type information of ChannelSpectrum to statically define number of FFT bins elsewhere.
TODO: Posting configuration message way too often. Fixing that is the next step.

Transmit ChannelSpectrum data through separate FIFO.
...

Perform frequency-domain windowing of spectrum.
...
Reduces sidelobes a bit, improves apparent resolution. Avoids windowing (more RAM and CPU) in baseband.
