Give Processors a run() function.
...
So main() can call it, start a Processor linked in to the baseband binary.

Move FIFO and write size to CaptureConfig structure.
...
Now configured from baseband, where write size and appropriate FIFO size is known.

Use CaptureConfig to share state between cores.
...
Remove awful FIFO_HACK.
TODO: Lots of repeated code...
TODO: Capture thread is signalled too frequently.

Further template BlockDecimator by element type, use for audio buffer.
...
Appropriating for use as a buffer accumulator that will save up enough audio samples to put into an audio DMA buffer.

Spectrum streaming control, spectrum attributes back in each frame.

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

Moved baseband temporary buffers back into class member variables.
...
Significant performance hit when declaring on stack. C++ wants to initialize std::array or even raw array with element constructors, was resulting in ~7% CPU utilization, for a buffer that was immediately written over anyway.

Move baseband FIR filter defs to common file.

They will likely be shared with multiple decimators/demodulators.
Also added normalized filter pass/stop values to each set of taps.
