Create HDR image from multiple variation of an image

[iNima]

@artob
Is your feature request related to a problem? Please describe.
I'd like to create an HDR image from multiple images with different exposure values.

Describe the solution you'd like
I've done it with Objective-C in Native iOS previously.
It would be great if we could do this out of the box with this flutter library as well.
For example, it could be something like this:

List<Image> images = [image1, image2, image3] //At least 3 versions of the same image each one with different exposure values.
List<double> times =  [0.25, 2.5, 5.0] // List of different exposure values of images above.
Image hdrImage = processHDR(images, times);

Kind regards,
Nima
