Cross-platform support for detecting if a process pid is active. Uses `process.kill(pid, 0)` on unix and `tasklist.exe` on Windows.

This method is extremely fast on Unix and the fastest I'm aware of for Windows.

**Usage**:

```js

const pid = require('is-process-active')

if (pid.activeSync(myPid)) {

  // do something if process is active

}

// or...

if (await pid.active(myPid)) {

  // do something if process is active

}

```

Note that on Unix it is [always synchronous](https://github.com/jdxcode/is-process-active/blob/master/src/unix.ts#L5). So if you never have to support Windows there is no reason to use the async version.
