Refactoring (#325)
* Refactor core

* Re-added tests

* Small fixes

* Add tests for acmetxt cidrslice and util funcs

* Remove the last dangling reference to old logging package

* Refactoring (#327)

* chore: enable more linters and fix linter issues

* ci: enable linter checks on all branches and disable recurring checks

recurring linter checks don't make that much sense. The code & linter checks should not change on their own over night ;)

* chore: update packages

* Revert "chore: update packages"

This reverts commit 30250bf28c4b39e9e5b3af012a4e28ab036bf9af.

* chore: manually upgrade some packages

* Updated dependencies, wrote changelog entry and fixed namespace for release

* Refactoring - improving coverage (#371)

* Increase code coverage in acmedns

* More testing of ReadConfig() and its fallback mechanism

* Found that if someone put a '"' double quote into the filename that we configure zap to log to, it would cause the the JSON created to be invalid. I have replaced the JSON string with proper config

* Better handling of config options for api.TLS - we now error on an invalid value instead of silently failing.

added a basic test for api.setupTLS() (to increase test coverage)

* testing nameserver isOwnChallenge and isAuthoritative methods

* add a unit test for nameserver answerOwnChallenge

* fix linting errors

* bump go and golangci-lint versions in github actions

* Update golangci-lint.yml

Bumping github-actions workflow versions to accommodate some changes in upstream golanci-lint

* Bump Golang version to 1.23 (currently the oldest supported version)

Bump golanglint-ci to 2.0.2 and migrate the config file.

This should resolve the math/rand/v2 issue

* bump golanglint-ci action version

* Fixing up new golanglint-ci warnings and errors
