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.

+``future.builtins``
+===================
+
+The ``future.builtins`` module is also accessible as ``builtins`` on Py2.
+
+- ``pow()`` supports fractional exponents of negative numbers like in Py3::
+
+    >>> from builtins import pow
+    >>> pow(-1, 0.5)
+    (6.123233995736766e-17+1j)
+
+- ``round()`` uses Banker's Rounding as in Py3 to the nearest even last digit::
+
+    >>> from builtins import round
+    >>> assert round(0.1250, 2) == 0.12
