[BREAKING CHANGE] v1.0.4: Code cleanup with golangci-lint

This release introduces breaking changes

I am currently implementing code standards across all my code bases by introducing a golangci-lint workflow. This release applies this workflow to go-hibp. Unfortunately this introduces a breaking change be renaming all methods and references that previously had Api in it to API and Http to HTTP.

Please update your code accordingly.

What's Changed

• Fixes and test coverage by @wneessen in #18
• Implement a golangci-lint workflow and the accordingly GH action by @wneessen in #19
• Better test coverage by @wneessen in #20
