Wrong type of AlternativePaymentMethods start and initiate

[jochem-van-eldijk]

Passing the options object to the start method does noting:

recurly-js/types/lib/alternative-payment-methods.d.ts

Line 86 in 3868a4a

start: (data: AlternativePaymentMethodOptions) => Promise<void>;

instead it should be passed when creating a AlternativePaymentMethodsInstance here:

recurly-js/types/lib/alternative-payment-methods.d.ts

Line 104 in 3868a4a

export type AlternativePaymentMethods = () => AlternativePaymentMethodsInstance;

you can see this also being done in your example repo: recurly-integration-examples/public/alternative-payment-methods/ideal.html
