Anthropic Claude Support

[Michael]

Came by your library recently and absolutely love it! I have been using JsPyBridge to use LiteLLM in my OSS project Magick, however it has had some issues and complexities. I would love to switch to modelfusion. My biggest blocker is that I use Anthropic heavily, and to a lesser extent Gemini.

I noticed there was a closed issue for Anthropic support, but I see it was at some point removed as it isn't in the docs or in the code.

Any work on adding Anthropic support? I could possibly contribute back as well if there is no work on Claude or Gemini.

Thanks! And awesome work.
