text: Title: Redis connector
  Body: ### 🚀 The feature
  
  Allow pandasai to connect to Redis and perform search over databases. 
  
  ### Motivation, pitch
  
  Currently there are SQL connectors for pandasai, but Redis is also a popular database.
  Recently Redisearch module added vector storage and search capability, which I think is a valuable addon for pandasai for searching within databases containing multiple long documents.
