> Reliably get the terminal window size

Because [`process.stdout.columns`](https://nodejs.org/api/tty.html#tty_writestream_columns) doesn't exist when run [non-interactively](http://www.tldp.org/LDP/abs/html/intandnonint.html), for example, in a child process or when piped. This module even works when all the TTY file descriptors are redirected!

Confirmed working on macOS, Linux, and Windows.

```
