Use matched filter for AIS GMSK demodulation demo.
...
Less than optimal for plain FSK, but flexible enough to also support GFSK/GMSK. Not at all optimized for SIMD instructions, so may not perform adequately at Bluetooth/GSM rates.

Matched filter implementation.
...
Essentially a complex FIR filter that's more flexible than the ones already in the code base. Refactor?!
