HTTP/2 support

[Medvezo]

How can I enable HTTP/2 on every request? Passing http2: true to options doesn't work

Passing { http_version: "2" } works, but still doesn't send HTTP/2 request. Here is the output of curl --version

After voracious digging I managed to make it work. For future lurkers:
response = Typhoeus.get("https://example.com", http_version: :httpv2_0, verbose: true)

To test it, you can also run response.http_version, which will return "2" (if you haven't noticed it from the cURL debug info).
