Support OpenAPI v3.0.x

[shadowhand]

Any idea what it would take to support OpenAPI 3? I assume it would impact request/response definition at minimum. Have this been explored at all?

@shadowhand As a matter of fact, one of my closed source project already support OpenAPI v3, I already planed to merge both project into eleven-labs/api-validator. It's not feature complete as the spec goes but it's good enough to be shared with the community. I'll have some free time this weekend to work on it.

It has a quite busy weekend, I'll try to contribute that feature this week, stay tuned :)
