[Feature Request]: Integrates Infinity with RAGFlow

Is there an existing issue for the same feature request?

Describe the feature you'd like

Besides vector search and fulltext search, Infinity also support sparse vector search, tensor search and RRF reranker in v0.2.0. Now, we can integrate Infinity as the database of RAGFlow.

Also refer to: infiniflow/ragflow#697, infiniflow/ragflow#1308

[JinHai-CN]

Because the storage format will be changed in Infinity 0.3.0, integrating Infinity into RAGFlow is postponed in 0.4.0.
