tools: fit_image: Use fit_image_get_data_and_size for getting offset/size 

This is very similar to fit_image_get_data but has the benefit of working
on FIT images with external data unlike fit_image_get_data. This is
useful for extracting sub-images from type of FIT image as this would
previously just silently fail. Add an error message also so if this
still fails it is easier to find out why.
