Move from JSON to SQL DB

Better save the scraped content in a DB.

JSON files cannot be directly imported on SQL DB. Possible solutions discovered till now :

1. convert JSON files to a well-formatted supported file and import
   https://docs.phpmyadmin.net/en/latest/import_export.html#
2. Loop through the data and insert using forms manually

I also feel separate tables for each conference should be used.

We'll create a simple script to read in a JSON and dump it to a sqlite file.
This should be pretty simple with a few lines of code.
