This patch improves the performance of `imgaug.augmenters.arithmetic.multiply_elementwise()`. The performance improvement is roughly between 1.5x and 10x. The effect is stronger for smaller images and denser matrices of multipliers (i.e. `(H,W,C)` instead of `(H,W)`). This change affects `MultiplyElementwise`. Add functions: * `imgaug.augmenters.arithmetic.multiply_elementwise_()`.
