Check in `future` package

I hit some issues installing Whisper and had to embed this package.
I haven't taken the time to deeply understand what's going on. I think
that embedded Python follows different rules about resolving module
paths than regular system Python.

Basically, `future`'s setup.py has a line like `import src`, where
`src` is a module inside future (like `future/src/__init__.py`). This
doesn't work unless we put that directory on the search path.
