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

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...)
