Support recent Windows 10

A recent upgrade to the Windows 10 console resulted in VT mode being disabled by default for child processes. This breaks the ansi escape codes being converted into color.

This answer on StackOverflow fixes it:

Here is an explanation of the change that was introduced: microsoft/WSL#1173 (comment)

And here are Python devs refusing to do anything about it in the python interpreter:
https://bugs.python.org/issue29059

So for this module it'd be great to add:

import ctypes

kernel32 = ctypes.windll.kernel32
kernel32.SetConsoleMode(kernel32.GetStdHandle(-11), 7)

when the platform is on windows.

Microsoft's turn-off of ANSI coloring is definitely a bummer for colored text.

It's still an open question whether it's the responsibility of an ANSI-text generation library to try to fix it. I understand why it'd be convenient, and why it's annoying ANSI isn't enabled automatically. But twiddling Win32 control bits? That's a very specific and invasive side-effect—one that seems outside ansicolor's remit. Related: It's a side-effect that'd be hard-to-impossible for us to reliably test.

Fair enough and I agree - hopefully having this issue documented will help people find a solution more easily.
