Modify the discounts program parser

[mikehquan19]

Overview

A few discounts have more than one address, and the phone number format also vary across many different programs.

Modify the DiscountProgram schema's address to be []string and modify the discount parser so that a discount can contain multiple addresses, and normalize the phone number format to XXX-XXX-XXXX (or any format of your preference 😊, as long as they are consistent).

Note

I discovered this library https://github.com/dongri/phonenumber which could potentially normalize the phone format without us writing regexes ourselves. Use it if you need.
