Postpone clearing channel_spectrum_request_update until finished with data in array.

TODO: This feels kinda complex, and there's some repeated Processor code that needs to be refactored into a base class.

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.
