OpenAPI v3.0 Support

[philsturgeon]

I just noticed your awesome tool today when somebody shared it on the @apisyouwonthate slack channel, but it seems like its OpenAPI v2.0 only. Do you have any plans to upgrade?

If so, I'd love to link to this on OpenAPI.Tools. We only want projects which are either already on, or working towards, OpenAPI v3.0 support.
