Function warp 

pub fn warp(
    data: &[u8],
    width: usize,
    height: usize,
    channels: usize,
    depth: u8,
    target_w: usize,
    target_h: usize,
    mode: u8,
    replicate: bool,
    value: f32,
    inverse: &[f64; 9],
    affine: bool,
) -> Result<Vec<u8>, String>

分行逆映射避免整幅坐标临时数组，释放 GIL 后可独立并发执行。
