v0.13.0

This release is a bugfix release and includes mostly cosmetic changes to the Go codebase that were reported by various linters via golangci-lint. I fixed the CI to use the golangci-lint-action and created a configuration file to enable all linters, including gosec, except a few. All constructors and functions are now unexported and you can access them via either of these classes: Writer, Reader or Connection.

I addressed these issues:

• Fix all (feasible) linter errors
• Fix configuration objects in the example scripts
• Constructors and non-constructors needn't be exported
• Refactor and remove deprecated kafka-go functions

Also, @thmshmm was kind enough to fix a bug in #129 that I introduced in the byte array serializer. 🙏
