Should data be read from sqlite?

[blalop]

Currently, the input data comes directly from the documents the bank provides: built-in bbva2pandas reads this documents and generates a dataframe on demand.

This approach generates some issues:

• All documents must be available to the app
• bbva2pandas pip dependency
• time spent in bbva2pandas parsing

bbva2pandas allow the exported data to be exported in sqlite format. This app could use that format and use SQL queries directly to retrieve the data, rendering the app simpler.
