Summary: Hi,
I'm currently building an app that changes metadata, does some resizes, maybe watermarking ...etc. I want to use RCTImageStoreManager to store the original image in memory and allow me to command different modifications from javascript as it gives me more flexibility. As RCTImageEditingManager does for example.
But currently the RTCImageStoreManager uses UIImage to store the image, the problem is that UIImage losses metadata.
So i suggest we change it to NSData.
Additionally I added a method to remove an image from the store.

Summary:
Addresses #1534
When an image has a known width, but a height of 0 (which can happen if `flex: 1` is set on the `Image` element), `RCTDownloadManager` attempts to scale it to an invalid size, which results in a `NULL` `CGContextRef` and some scary warnings from UIKit:
```
<Error>: CGContextTranslateCTM: invalid context 0x0. This is a serious error. This application, or a library it uses, is using an invalid context and is thereby contributing to an overall degradation of system stability and reliability. This notice is a courtesy: please fix this problem. It will become a fatal error in an upcoming update.
```
This adds a check for zero width or height to the `RCTClipRect` function. If either dimension is zero, it is calculated based on the aspect ratio of the source image. This ensures that we don't try to create an invalid `CGContextRef`, and that images with an unknown dimension are still scaled, blended, etc.

Summary:
Merged RCTStaticImage with our internal RKStaticImage and ported over logic where assets are loaded at the optimal size and reloaded if the view size changes.
