Not able to add a key when producing.

There isn't an option to add a key to a payload when producing. It seems to be an easy fix so I have created a pull request.https://github.com/Superbalist/php-pubsub-kafka/pull/5

I was wondering if the current owners of this weren't able to maintain it whether it could be opened up to the community to support?
