Support recent Windows 10 about colors

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.
