I don't prefer introducing a third party lint so far, though I might change my mind later. Thoughts? @TotallyGamerJet

I think it can be helpful. Don't know which ones we'd want or not want though.

@mmorel-35 Though I'm just an Ebitengine fan, your pull request sounds rough to me. The PR should explain why each of these options should be introduced into this project. I recognized you're sending similar patches to other projects without explaining those reasons, which sounds spams to me given the cost that the maintainers need to confirm the details of those PRs.

I've narrowed the PR to only add two formatters check (no other linters) and to run it across a GOOS/GOARCH matrix to establish the mechanism. If you prefer different formatters, a different matrix I can adjust.

We need more discussion to introduce such a tool. Let me close this PR once.
