Is this a native `async function`?

## Example

```js
var isAsyncFunction = require('is-async-function');
assert(!isAsyncFunction(function () {}));
assert(!isAsyncFunction(null));
assert(!isAsyncFunction(function* () { yield 42; return Infinity; }));
assert(isAsyncFunction(async function () {}));
```

## Tests
Simply clone the repo, `npm install`, and run `npm test`
