text: Title: [DEV-1122] [feature proposal] Add native support for pandas API
  Body: For now, pygwalker kernel computation uses sql + duckdb for data queries. Another approach might be using the native pandas API for all those computations. Benefits of this implementation include:
  + Test and switch to different high-performance dataframe library, like modin, polars.
  
  It would be even better for the community if developers could customize their own query engines.
