Custom-search CLI script (#460)

Summary

Implemented a Python script that uses Google Custom Search API to perform queries and export results to CSV.

Description

This script implements a Google Custom Search scraper with the following features:

• Load API setting from setting.json (create the file if missing and allows adding the api key with --add_api_key)
