Work around apparent alignment bug in G++ 5.4.1?
...
Padding struct to be sizeof() % 4 == 0, because it was crashing the baseband... I think.

cde15e4271
Generalize fir_and_decimate_by_2_complex_fast.
...
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.
