Remove OS restriction

[aggregate1166877]

This library is useful for solving cross-platform concerns: it allows setting Bash-style env vars on Windows, and is completely ignored on Linux. It's a win-win.

The problem is that the package.json file disallows installation of this library on non-Windows machines by default, which means that NPM crashes with an OS-not-supported error. This makes no sense as non-Windows systems simply ignore the package if installed, meaning everything works correctly everywhere if the OS restriction is removed.

I forked this repo over a month ago, removed the OS restriction to allow installation on Linux, and have been using it with multiple projects on Ubuntu Linux. I have experienced no issues whatsoever.

Would you please considering removing the OS restriction from this library?

You wanna put this under "optionalDependencies".

Todo: I should clarify this in the README.

All these years using NPM and I didn't know optionalDependencies existed, and didn't see it in this repo's README. I'm a bit embarrassed now :p

I'll place it in optionalDependencies. Thanks for the great package!
