Support a callback function to detect text changes about react-native-drag-text-editor

[eneskarpuz]

Thanks @reggie3. I agree, it would be useful. I'm waiting for your PR to merge but you'd better check these before you submit a PR;
1- I'm not sure about using type annotations like (text: string) .

onChangeText={(text) => console.log(text)}

isn't it better ?
2- You can add your Callback Function to onText function on DragTextEditor.js like;

onText=(text)=>{
... 
const {
 onChangeText,
} = this.props;

if ( text && onChangeText ){
 onChangeText(text);
 }
}

Sorry about the string annotation, I copied and pasted the code sample from a typescript file.
It makes sense to use the functionality you already have to implement the callback. I'll submit a PR based on what you said above.

@eneskarpuz How about this:

  onText = (text) => {
    this.setState({ text }, () => {
      if (text && this.props.onChangeText) {
        this.props.onChangeText(this.state.text);
      }
    });
  };

This way, the data sent back from the callback is in sync with what is in the component state.

Thanks @reggie3! Looks like a good idea. I think it'd be better to talk this on a PR.
