Decodes a string of data which has been encoded using base-64 encoding.
Create a `Buffer` for the given string with base-64 encoding and use `Buffer.toString('binary')` to return the decoded string.
```js
const atob = str => new Buffer(str, 'base64').toString('binary');
```
```js
atob('Zm9vYmFy'); // 'foobar'
```
