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.

+Python 3:

+Maybe use on Py2:

+
+Long int syntax (e.g. 1000000L) is incompatible with Py3.
+We probably shouldn't shadow int with long on Py2 because then isinstance(1, int) is False
+
+Python 2's bytes object is nothing like Python 3's bytes object!
+Running test_bytes.py from Py3 on Py2 (after fixing imports) gives this:
