[Feature Request]: Importer Update to handle `improter-generated-from` marker

🔎 Request Details

With the recent update of #15 , improter-generated-from marker is added when using importer generate with --out flag.

Example:

$ importer generate template.md --out result.gen.md
$ cat result.gen.md
<!-- == improter-generated-from: template.md == -->
This is a generate demo

As shown above, the added marker holds onto which file was used to generate the given file, importer update can track back to the original file, and attempt to generate again.

This would be useful if importer generate is used to manage complex YAML files such as Kubernetes resources, and want to simply ensure all the files are up-to-date by running something like find . -name '*.md' -exec importer update {} \;.

It may be wiser to add a flag to enable/disable this feature - I'm not sure if it's better to have it turned on or off by default - having this feature is probably useful, but could be confusing if turned on by default.

If we were to handle this, we would also need to remove Importer Marker of importer-skip-update when generating to a separate file.
