Feature request: Requester Pays

[benyanke]

It would be great to allow the requests to be sent with requester pays.

Yes, this sounds like a useful feature. Thanks for your work here. Will review once complete.

Excellent. I have a proof of concept mostly working in #43 without the config option (aka - hardcoded to use requester pays).

I'll be testing that, and then integrating with config.
