an optimized cached image for expo base on expo file system

## Fast image for expo based on expo file system


1. `expo install expo-file-system`
2. `yarn add expo-fast-image`
3. `import ExpoFastImage from 'expo-fast-image'`;
4. 
```
<ExpoFastImage
  uri='image uri' // image address
  cacheKey='unique key' // could be a unque id
  style={'custom style'} // your custom style object
  // any supported props by Image
/>
```

**Note**
If you `update` your image (which `uri` maybe changed), then you need to update the `cacheKey` too (that's **important**).
Because if you dont update the `cacheKey`, on that time it will load the **old** cached image
