Polyfill for events.EventEmitter.prototype.off in node versions < v10

node v10.0.0 added support for a built-in `events.EventEmitter.prototype.off`:

This package provides the built-in `events.EventEmitter.prototype.off` in node

v10.0.0 and later, and a replacement in other environments.

This package implements the [es-shim API](https://github.com/es-shims/api)

interface. It works in an ES3-supported environment and complies with the

[spec](http://www.ecma-international.org/ecma-262/6.0/).

## Usage

### Direct

```js

const off = require('events.off');

// Use `off` just like the built-in method on `events.EventEmitter.prototype`

const events = require('events');

const emitter = new events.EventEmitter();

const handler = () => {};

emitter.on('foo', handler);

// Use `off`

off(emitter, 'foo', handler);

```

### Shim

```js

require('events.off/shim')();

// `events.EventEmitter.prototype.off` is now defined

const events = require('events');

const emitter = new events.EventEmitter();

const handler = () => {};

emitter.on('foo', handler);

// Use `emitter.off`

emitter.off('foo', handler);

```

or:

```js

require('events.off/auto');

// `events.off` is now defined

const events = require('events');

const emitter = new events.EventEmitter();

const handler = () => {};

emitter.on('foo', handler);

// Use `emitter.off`

emitter.off('foo', handler);

```
