cv.min and cv.max bindings

Hi there,

Great job with opencv4nodejs!

Feels wrong to ask for more, but any thoughts to implementing cv.min() and cv.max() that compare 2 img-arrays and return an img containing the min or max values across all pixels respectively.

Here are the original docs:
https://docs.opencv.org/2.4/modules/core/doc/operations_on_arrays.html#min
https://docs.opencv.org/2.4/modules/core/doc/operations_on_arrays.html#max

You already have cv.mean cv.sum cv.median, so I wonder if cv.min() and cv.max() are declared elsewhere or were replaced by different functionality?

If not, is there a way to reproduce such functionality without doing something unseemly like iterating through pixel-by-pixel?

I also tried to look in your docs at but https://opencv4nodejs.herokuapp.com/docs/ but it seems like it's down.

Anyway, thanks a lot for the fantastic work!

Cheers.
