Any plans to upgrade to go 1.18?

[Vedadiyan]

Is there any plan to upgrade to go 1.18 so that generics can be introduced for Encoded Connections? That allows for a generic Request function that would be more convenient to use.

I would like create a pull request for a version that I modified and I added a few functionalities for Encoded Connections which require go 1.18

1- A generic version of Request which returns a wrapped result under EncodedMsg
2- I added Headers to the new EncodedMsg struct
3- I added another version of Publish to accept EncodedMsg so that headers could be used as well

I required these features, because I would like to somehow deliver a response when something goes wrong in the subscriber and a response cannot be produced. Then I can report the error through headers. But the existing version does not allow that. (Headers are available for plain connections and not encoded connections)

We are exploring a bit, we would not use the encoded conns and more likely would introduce a better way of chaining handlers together, similar to "middleware" for HTTP.
