[Classes.RequireMultiLineMethodSignature] Option when has attributes

[yguedidi]

Would it be possible to have a new option hasAttributes for SlevomatCodingStandard.Classes.RequireMultiLineMethodSignature? Goal is to force multi line method signature when there is at least one attribute involved in the parameters
