Windows compatibility: replace posix_isatty() with stream_isatty()

[underdpt]

Hello,

Giving it another try to check if there's a way to make this package windows compatible, i found stream_isatty() which is described on php documentation as a posix_isatty() replacement, and is windows compatible.

What do you think?

Hey @underdpt

Sounds promising, I'm not 100% sure what else might need refactoring to support windows but I'd be interested to see if that gets over any initial hurdles. I have little to no experience with windows around this area so would welcome any assistance, prototyping etc

Also, looks like that function is only available in PHP 7.2, currently we support 7.1. I'm happy to drop support for 7.1 though. But as @mikeymike says, I don't think that will be last issue. In fact, we probably added that because we couldn't get it to work on windows.

I'm on vacation in two weeks. Will try to make a PR then and run the tests to see what other issues arise. I have a project that runs on windows where this would be very useful, so if the tests passes, will try a quick integration to check if it works in a real life application.
