Optionally accept idempotency-key from the caller?

[k2n]

Hi,

I was wondering if sequence SDK can be enhanced to accept optional idempotency-key as an argument of request.

The use-case is that we'd like to accept deposit remitted via wire transfer only once. If I can use the wire-transfer transaction id as an idempotency key, then it would prevent the multiple submission from happening due to double submission or retry logic.

Thanks,
