Should NetworkImage be mandatory to use swift-markdown-ui?

[freak4pc]

Hey there, thanks for the incredible library!

I was wondering if you'd consider having a variant that doesn't use NetworkImage.

For example I have multiple use-cases that are guaranteed to not have any images in the markdown at all, and there's no need for me to carry this dependency.

Maybe even better - allow to do it as part of the configuration, provide your own way to load an image (Be it your own URLSession, or existing loading mechanisms in the host app - like Nuke, Kingfisher, et-al).

The point here is:

1. If you don't need images at all, allow opting out of the dependency; and
2. If you do need images, not have two dependencies that do image loading (if the app already has one, like most would).

What do you think?
