Add AmazonShippingRateProvider for fetching rates

Introduces the `AmazonShippingRateProvider` class implementing the `IAmazonShippingRateProvider` interface to retrieve shipping rates from the Amazon API. Updates the `ShipDate` property type in `AmazonShippingApi.cs` from `DateTimeOffset` to `string`. Adds a new folder for dependency injection in the project file. Removes the unused `Class1.cs` file. Includes additional using directives in relevant files for improved functionality.
