Scrollview zoom option for android

[ktjd123]

Introduction

Hi, I think it would be great if scrollview's zoom option has android support.

Details

Since there is so lack of lib for react native zoom lib, It is so hard to implement pinch to zoom function for android.

The zoom function for ios is great and It would be even greater if we could implement using just scrollview. (with same code)

Discussion points

Android support for Scrollview's zoom options.
