haha, fixed that artifact too. Strange flickering line in the spectrum at -100 dB was caused by reading some samples out of region

Precalculate FFT window
Before this calculating FFT window was taking much more CPU time than calculating the FFT itself.

Renamed convert_f_i16 -> convert_f_s16 and convert_i16_f -> convert_s16_f. (csdr also triggers for the original functions, but they are deprecated.

Now at least we get a continuous output signal from shift_addfast_cc/NEON. And we get a good result if the shift_rate is 0! (Okay, we get a bad result for anything else...)
