[FEAT] 9 Get Top Familiar Entities

[seyeong-han]

Update

Now, we are leveraging our Entity Knowledge Store by selecting only frequently called entities to give more user-relevant answers!

To Reviewers

• The problem of llm input was 'memory_stream' and 'entity_knowledge_store' dictionary information. We popped those dictionaries to remove them.

  llm_message_chatgpt.pop("knowledge_entity_store")
  llm_message_chatgpt.pop("memory_stream")

LGTM! Also added top 20 to the streamlit app for the demo.
