I added `nats_publish_request` which calls the `natsConnection_PublishRequestString` to send a request to the NATS server with a `reply` string so the response can be easily replied back.

I tested in Lua and the native route, not sure if it's the right way to implement. I can update docs if it sounds good.

Thanks.
