Functions
float	espectre::calculate_mean (const float *values, size_t n)
	Calculate mean of an array.
float	espectre::calculate_median_float (float *arr, size_t size)
	Calculate median of a float array (sorts array in-place).
float	espectre::apply_cv_normalization (float std_dev, float mean)
	Apply gain-invariant normalization to standard deviation.
float	espectre::calculate_turbulence_from_variance (float variance, const float *values, size_t count)
	Calculate turbulence from variance with gain-invariant normalization.
MeanVariance	espectre::calculate_mean_variance_two_pass (const float *values, size_t n)
	Calculate mean and variance in one two-pass sweep (numerically stable).
float	espectre::calculate_variance_two_pass (const float *values, size_t n)
	Calculate variance using the two-pass algorithm.
float	espectre::calculate_magnitude (int8_t i, int8_t q)
	Calculate magnitude (amplitude) from I/Q components.
uint8_t	espectre::normalize_amplitude_profile (const float *amplitudes, uint8_t count, float mean, float *out)
	Write the mean-normalized amplitude profile into out.
