963b6e257a FFT twiddles can be used for all K <= table length.
Change assert to allow FFTs < 8.

Jared Boone
54e59cc224 Hard-code K=8 FFT twiddle constants for now.
So low on baseband RAM! This eliminates the sin_f32() function and table, which is only used in the FFT, for the moment.

07cd99d85d 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.)

b8726b6ecf Un-bitfield PinConfig, GCC 5 didn't like it.
