Move SGPIO configuration and control to baseband firmware.
...
Addresses long-standing and annoying bug where SGPIO DMA channel would not disable -- and not configure cleanly next time it was needed. My theory is that the DMA channel couldn't disable until it got a request from the peripheral, and sometimes the peripheral was disabled before that last request.
Anyway, the baseband firmware should control the SGPIO, methinks, despite the impact on baseband code size.

Permit decimation_factors other than 2.
Permit tap counts != 64 (but still must be multiple of 8).
Half the amount of tap memory required.
Performance is significantly degraded due to greater flexibility -- most likely due to separate sample buffer shift phase, instead of performing shift during output sample calculation.

MatchedFilter improvements
...
Use single set of taps for positive and negative filters.
Reverse taps (since new samples are pushed into buffer from the high end).
Make complex multiply explicit to avoid fancy but irrelevant arithmetic checks.
Compute negative filter from conjugation of positive filter taps.
Move filter power and difference calculations into MatchedFilter.
