install_requires 'future' even in a python3 environment

(arrived here from serverless/serverless-python-requirements#285 (comment))

I'm experiencing lambda python packages that are much larger than they should be in a Python3 environment because Jose depends on future, even though future is only needed in a python 2.6 environment.

python-jose/setup.py

Line 68 in 7bc6b98

install_requires=['six <2.0', 'ecdsa <1.0', 'rsa', 'future <1.0']

Is this a limitation inherent to python? How to avoid pulling in future?

Fixed in #134.
