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.

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.)
