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. A related PR can be found here https://github.com/lwansbrough/react-native-camera/pull/100.
