Data from the underlying API not exposed by SDK classes

1. client.qualifications().checkEligibility() accepts an option to expand redeemables, but the expanded values do not appear to be available in CheckEligibilityResponse.getRedeemable().getData().

    private static final Option EXPAND_REDEEMABLES_OPTION = Option.builder().expand(List.of(Expand.REDEEMABLE)).build();
    ...
     Customer customer = toVoucherifyCustomer(company);
    CheckEligibility check = CheckEligibility
            .builder()
            .customer(customer)
            .scenario(Scenario.AUDIENCE_ONLY)
            .option(EXPAND_REDEEMABLES_OPTION)
            .build();
   
    CheckEligibilityResponse eligibility = client.qualifications().checkEligibility(check);
   

RedeemableDataResponse does not have a getName or getBanner ... even though these values are returned in the underlying API call.

2. client.stackables().validate does not appear to expose the applied_discount_amount property in the OrderResponse class, even though the value is present in the underlying API call to /v1/validations. The equivalent OrderItemResponse.getAppliedDiscountAmount() is there, but OrderResponse just has getDiscountAmount() and no getAppliedDiscountAmount().
