Feature Request: Download all preview images when Scanning (even if a preview is present)

Describe Issue

"Scan Models for Civitai" doesn't download all model example images when there are images present already. If the user used a previous (or different) version of this extension, for some models, only a single preview image has been downloaded.

Upon clicking "Scan" in the extension tab, the expected behavior is that it will download all the preview images, including ones the user doesn't have. However, if there's a preview image already, it won't download the rest. Therefore, sometimes the user will think that all the info (including preview images) for all the new models has been updated, but in fact, the images weren't included.

I think this is for models where the info and previews were generated before "downloading all sample images" was implemented.

Screenshot for UI issue

An option for "Update previews (will not overwrite current preview images)" should be added.

When checked, it should scan and download additional image previews if they haven't been downloaded already. It should also not overwrite the user set preview image (for example: model.png for model.safetensors) or any current image.
For example, if there's model.example.0.png and model.example.1.png and the Civitai page has additional example images, example 0 and 1 shouldn't be overwritten.

Thank you and I hope this can be implemented so it can make the user's model info more complete.
