Resolving image version when it is defined as argument

[Ferror]

Introduction

Hi! Big kudos for creating this tool. I would like to suggest a feature. It is popular in my area that we specify versions of images as arguments. So they can be easily changeable. What is seen is that dockerfilegraph does not resolve them and for graphs, I would expect them to be resolved. I am not aware of how the tool works itself, but maybe we could analyze the Dockerfile after the first compilation? After the arguments are resolved. Please let me know what you all think about it.
