The challenge is to write the logic for a delivery date calculation within the ShippingDates class.

2. All deliveries are on a 3 day service, there is no time calculation for simplicity.
3. No parcel can be dispatched on a Saturday or Sunday.
4. No parcel can be delivered on a Saturday or Sunday.
5. The code must pass all tests
6. Only work in ./src/ShippingDates.php
7. Code must conform to PSR-1 and PSR-2 standards
   1. https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-1-basic-coding-standard.md
