Mollie API 4.3.0.0

New features:

• Add support for the BillingAddress property on PaymentRequest.
• Add support for the ShippingAddress property on PaymentRequest.

Technical improvements:

I've received feedback regarding the usage of the required parameters I've added in version 4 of the library. In general, the reception has been positive. However, I've also received feedback from @martijnmelchers and @JoKeKt that it makes the library difficult to use when creating payment method specific PaymentRequest objects. A common use-case is to create payment method specific PaymentRequest objects using a switch statement on a payment method. However, since certain properties are now required, it was necessery to repeat these properties in the switch statement, resulting in a lot of duplicate code.

I've implemented a solution in the form of a constructor overload on all payment specific PaymentRequest objects that you can use to avoid this code duplication. An example can be found here
