OpenCV had Stream ready([cuda/arithm.cpp](https://github.com/hybridgroup/gocv/blob/1ce30bf65f8ede198102241f5103e9af2e89bcf6/cuda/arithm.cpp#L101), [cuda/arithm.h](https://github.com/hybridgroup/gocv/blob/1ce30bf65f8ede198102241f5103e9af2e89bcf6/cuda/arithm.h#L26) and [opencv multiply](https://docs.opencv.org/master/d8/d34/group__cudaarithm__elem.html#ga497cc0615bf717e1e615143b56f00591)), but GoCV did not have `MultiplyWithStream`. So I added the function...

## Description The description says that the package supports OpenCV v4.8.1, but right now the [calibration flags](https://github.com/hybridgroup/gocv/blob/release/calib3d.go#L16) correspond to OpenCV [3.4](https://docs.opencv.org/3.4/db/d58/group__calib3d__fisheye.html). [Flags](https://docs.opencv.org/4.7.0/d9/d0c/group__calib3d.html) of OpenCV 4.7.0.
