Go SDK for API

[Suhaibinator]

I wrote a Go SDK for interacting with the Postal API. Wanted to share it here and recommend that it be added to postalserver if others approve. It has 0 dependencies outside of the Go standard library and also has 92% test coverage :).

I'm happy to cede control of it as well of course.

It looks like https://docs.postalserver.io/developer/client-libraries already links to another Go library so not sure how different they are and whether it is worth linking to both

Mine has more test coverage and documentation :D
