Support for YAML struct tags instead of JSON. #849

For my use case I'd like the struct tags to be for YAML instead of JSON. I've tried 'applicaion/yaml' in the response type of the API spec had a look at the code and it doesn't seem this project supports that out of the box.

What I get

type Device struct {
	Messages *[]Message `json:"messages,omitempty"`
}

What I want

type Device struct {
	Messages *[]Message `yaml:"messages,omitempty"`
}

If this isn't already a feature, or on the road map I am happy to fork and give implementing this a crack. Just wanted to get a second pair of eyes to confirm.
