Any chance to port to prompt_toolkit 3?

Hi!

I just learned about this little gem today and ended up trying to write a Gentoo Ebuild for http-prompt, but one thing missing from the official Gentoo tree is a prompt_toolkit < 2.0.0... Is there a chance to support prompt_toolkit 2 or 3, or are there tons of work to migrate? (Hmm... The "Why all the breaking changes?" header on their migration page isn't a good sign I guess... ;) )

AFAIK, Gentoo is trying to move on from Python <3.6 (or <2.7), so overlaying a prompt_toolkit version < 2.0.0 isn't really a good option...

But since I'm not at all a Python coder, I am a bit wary of even trying myself to be honest.
