add AI/ML API as provider #929

Hi!

I'm Sergey from the Integrations team over at AI/ML API, a startup with 150K+ users, providing over 300 AI models in one place

Your project looks dope, so we'd like a native integration. We already got integrations with Langflow, AutoGPT, and LiteLLM - so our integrations team is pretty seasoned :)

Say you're interested, and we'll test the compatibility, update the code/docs to include us, create a PR and add a tutorial on using lightllm with AI/ML API to our docs

If you guys give us a green light, we could get on it 👷
