Add Liquid AI service provider

Is your enhancement related to a problem? Please describe.

Liquid AI recently launched their Liquid Foundation Models (LFMs) and can be integrated via Lambda's Cloud API (compatible with the OpenAI API) and setting the model to /models/LiquidCloud leveraging. There are some significant performance improvements here compared to transformer-/RNN-/hybrid-based generative AI models and worth testing out ahead of actually bundling into ClassifAI.
