Parsers should be able to return results for multiple tools

[sagikazarmark]

Golang CI is a great tool, collecting a number of Go linting tools in one binary. It is capable of outputting a checkstyle format (and a custom json format as well) which can contain the actual linter which raised an issue.

It would be nice, if the actual tool could be detected by the parser itself.

golangci-lint reports linter name in the message, so it should be fine for most cases.
