Idempotency support

[artemijan]

I've noticed that this library supports Idempotency feature. But accordingly to adyen documentation it should be handled in different way, see https://docs.adyen.com/development-resources/api-idempotency.
I just need a way to pass this header (uuid) though the library, so this header can be controlled from my application.

Thank you.

We're also looking for this feature.

I ended up with implementing this feature on my own 21f5f0b.

I found this article which describes the existing implementation (in 4.0.0) as obsoleted by Adyen: https://www.adyen.help/hc/en-us/articles/360012846739
