how to use this linter with golangci-lint

[kyoh86]

I've to write it in README.md

looppinter is not bound in golangci-lint since
golangci/golangci-lint#1041 (comment)

If you are going to include only one, please include exportloopref. No body wants false positives from their linter.

I think so too.
But if anybody want to use this one, I want help them.

（:thought_balloon: どうでもいいけど、Scopelintを潰してこういう二択にしたのが、
結果的にこうして誰かの選択の余地を生み、そして実際に選択してもらえたという体験は嬉しいものだ）

golangci-lint uses go 1.12. I wont use old go.
I give up building plugin for golangci-lint.
