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.

Rebake of AM, NFM demodulators -- more flexible filtering/configuration.
...
Also make SpectrumCollector dynamically configurable.
Add deemphasis filter to NFM.
