[Feature Request]: Integrate Triplex for cheaper triplet extraction

[emrgnt-cmplxty]

Is your feature request related to a problem? Please describe.

Triplex [https://huggingface.co/SciPhi/Triplex, https://www.sciphi.ai/blog/triplex] makes it 98% cheaper to extract knowledge graph triples when compared with gpt-4o, with better performance. I would like to see support for this model merged into GraphRAG.

Describe the solution you'd like

Where gpt-4o is being used to extract knowledge graph triplets, it would be great to have a configurable flag that allows a local version of triplex, served via ollama, to be ran instead.

Additional context

I contributed to the creation of triplex and am very interested in contributing to make triplex accessible in the GraphRAG repository.
