> Read stream to buffer or string
## Install
```
$ npm install --save read-all-stream
```

```js
var read = require('read-all-stream');
var stream = fs.createReadStream('index.js');
read(stream).then(function (data) {
console.log(data.length);
});
read(stream, 'utf8', function (err, data) {
console.log(data.length);
//=> 42
});

### API
#### read(stream, [options], [callback])
If callback is omitted, Promise will be returned.
##### stream
*Required*
Type: `Stream`
Event emitter, which `data` events will be consumed.
##### options
Type: `object` or `string`
If type of `options` is `string`, then it will be used as encoding.
If type is `Object`, then next options are available:
##### options.encoding
Type: `string`, `null`
Default: `'utf8'`
Encoding to be used on `toString` of the data. If null, the body is returned as a Buffer.
##### callback(err, data)
Will be called after stream is read.
###### err
`Error` object (if `error` event happens).
###### data
The data in stream.
