Transmit ChannelSpectrum data through separate FIFO.
...
Allows handling of data during LCD "vertical retrace", independent of other baseband->application messages. A bit kludgy still...

Move BasebandStatsCollector code into .cpp, as much as possible.

Still have template for callback, but hopefully will mitigate bloat when BasebandStatsCollector is used in multiple places.

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.

Removing baseband MessageHandlerMap.
...
It's a bit heavy (362 bytes smaller with switch/case implementation), hard to access to add/remove handlers, doesn't bubble events like I'd like. (I'm going to bubble events to the baseband processor shortly.)
