HTTP2 support?

[datoga]

Curl has http2 support since some time ago https://curl.se/docs/http2.html. In fact, it is enabled by default when https is used.

Is it planned to get this options supported in the project?
If not, I would like to understand what it is needed to enable it.

Supporting these new options involves executing the pre-processor programs like: #51 or is it needed an extra effort to enable it?

Of course, I suppose that supporting some of the new HTTP2 features (streaming, bidirectional, etc.) will require an extra effort, but maybe a "light" version of http2 support would take advantage of most features in HTTP2 (speed, compression, security, etc.).
