Summary:
Allow modifying iOS image cache limits. Currently the image cache imposes some strict limits:
[NSCache.totalCostLimit](https://developer.apple.com/documentation/foundation/nscache/1407672-totalcostlimit?language=objc) of 20MB.
Single Image Size Limit of 2MB (bitmap size).
This may not be enough for applications that make heavy use of images. With this commit it is possible to fine tune them to the applications need.
This can be set for example in the App Delegate with:
```objc
RCTSetImageCacheLimits(4*1024*1024, 200*1024*1024);
```
This would increase the single image size limit to 4 MB and the total cost limit to 200 MB.
