Feature request: Add support for "setOption('jpeg:size', '800x800');"

Issue description

Can you please add support for $imagick->setOption('jpeg:size', '800x800');? (the 800x800 needs to be configurable by the user).

It needs to be called before opening an image and helps tremendously when working with large images. It minimizes the memory usage when loading the image.
