Function ispc_downsampler::downsample

pub fn downsample(
    src: &Image<'_>,
    target_width: u32,
    target_height: u32
) -> Vec<u8>

Runs the ISPC kernel on the source image, sampling it down to the target_width and target_height. Returns the downsampled pixel data as a Vec<u8>.

Will panic if the target width or height are higher than that of the source image.
