Functions
void	fers_signal::upsample (const std::span< const ComplexType > in, const unsigned size, std::span< ComplexType > out)
	Upsamples a complex waveform with zero-stuffing followed by Blackman FIR filtering.
std::vector< ComplexType >	fers_signal::downsample (std::span< const ComplexType > in)
	Low-pass filters and decimates an oversampled complex waveform back to base rate.
