Reading an image file and returning Uint8Array or Uint8ClampedArray

Hello,

I am using _react-native-fs_ to read images that I retrieve with the ImagePicker of React Native.

I want to convert these images into Uint8Array (or Uint8ClampedArray even better), and for now I do it like this:

```
RNFS.readFile(result.uri, "base64").then(data => {
base64res = base64.parse(data); // -> Uint8Array
});
```

But, I want have a very fast code, so, is there a function like `readFile `or an option of `readFile` that **directly** return _Uint8Array_ ?

Thank you
