Function convolve2d_f32 

pub fn convolve2d_f32(
    src: &[f32],
    dst: &mut [f32],
    rows: usize,
    cols: usize,
    kernel: &[f32],
    k_rows: usize,
    k_cols: usize,
    normalize: bool,
) -> Status

Performs 2D spatial convolution of src image (rows x cols) with a k_rows x k_cols kernel.

If normalize is true, the convolution output is divided by the sum of the absolute kernel weights.
