[Civitai] Image ID not available for all Civitai extractors.

[austblack88]

I noticed that, when scraping images, the image id keyword isn't available for every subcategory in the Civitai extractor. For instance, it will be available for the "user-images" extractor:

...
hash
  U9C?Gs^*009G%L~Vs;4:00WV?bxa_3D*D%%M
height
  1024
**id**
  383346
meta
  None
...

but not for the "model" extractor (like when extracting images from a model's gallery).

Would it be feasible to include this in the other extractors?

For "api": "rest" (default), the numeric ID should be available as filename. I should probably give it a proper id name, though.

I did try to fallback on the filename, but it's not always the same as the image id.
