How can I know the source position of AutoLink node?

Hi,

I'm trying to rewrite auto links in Markdown document using goldmark. I need to get the source position of AutoLink node. However, AutoLink node contains Text node as its private field, not as a child. BaseInline.Lines doesn't help this issue since it cannot be called with inline nodes.

How can I get the source position of AutoLink node?

In case it's not possible, I'd like to suggest to add a new method to get a source position of the underlying text node. I created a PR for convenience: #442

Closing as I somehow could find a workaround for this.
