Method to resize an image based on the provided options and return the resized image details. Please note that the resized
image will respect the aspect ratio of the original image and will be resized to be equal to less of the provided maxWidth or maxHeight.
If the image both width and height are less than the provided maxWidth and maxHeight, the image will not be resized
and the original image details will be returned with resized as false.
If either maxWidth or maxHeight is not provided or 0, this parameter will be ignored (not used) and the image will be
resized based on the provided maxWidth or maxHeight, accordingly.
Please note that either maxWidth or maxHeight must be provided to resize an image.
