DisplayType Vector3Stamped

[goretkin]

Is there a reason there is no Vector3Stamped display type or is it just a matter of adding the feature?

I'm not aware of a reason, but it might overlap with another, similar type which people more commonly use.

I see you've opened a pull request, so I'll close this in favor of that: #860
