count()

std::vector< double > MayaFlux::Kinesis::Discrete::count	(	std::span< const double >	data,
		size_t	n_windows,
		uint32_t	hop_size,
		uint32_t	window_size
	)

Sample count per window (as double for pipeline uniformity)

Returns the actual number of samples in each window, which may differ from window_size at the final window if data does not divide evenly.
