Subtract centroid from `v`, storing result in `out`.

    /// Subtract centroid from `v`, storing result in `out`.
    fn center(&self, v: &[f32], out: &mut Vec<f32>) {
        out.clear();
        out.extend(v.iter().zip(self.centroid.iter()).map(|(&x, &c)| x - c));
    }

    /// Pack signs of `centered` into bytes (1 bit per dim, MSB-first within
    /// each byte).  Returns byte vector of length `dim.div_ceil(8)`.
