Add Advert Prompt Table Generator

[jmazur]

I was looking for a convenient way to generate the advert prompt table. One main goal was to make it easy to support multiple terminals in the future. The generator takes in a CSV and an optional terminal ID and outputs the table.

This change addresses the need by:

• Add a default advert prompt CSV, this is based on the current default advert prompt table in the tables/default folder.
• Add an advert prompt table generator.
