Function compute_array_stats 

pub fn compute_array_stats<S, D, F>(
    array: &ArrayBase<S, D>,
) -> CoreResult<ArrayStats<F>>
where
    S: Data<Elem = F>,
    D: Dimension,
    F: Float + Display,

Compute summary statistics for a flat array.

Handles NaN and Inf gracefully: they are counted but excluded from min/max/mean/std calculations (which use only finite elements).
