Python 2.7 support; RHEL support

What operating system are you using for this?

The default amazon ami uses python 2.7 and the following line fails

return 2000 + (int.from_bytes(hashlib.sha256(i.encode()).digest()[-2:], byteorder=sys.byteorder) // 2)

as python 2.7 does not have int.from_bytes() attribute.

I got tripped up by this because it looks like the currently released version (0.2.1) doesn’t have the fix for Python 2.7. I figured out that I could install directly from git like this:

pip install git+https://github.com/kislyuk/keymaker.git

I have released v0.3.3 from master.
