support display local image

[zhangwilling]

This is an enhancement.

some images are not remote, such as '/private/var/mobile/Containers/Data/Application/33750DB7-00A8-4537-837D-7747800EB4B5/tmp/react-native-image-crop-picker/459488B7-E263-4325-95DC-AD539779FBAC.jpg'

we can judge if image source is a remote at here.

react-native-img-cache/src/index.tsx

Line 177 in c4ffc42

protected getProps() {

If the image is local, we don't need to invoke download function and notify.

react-native-img-cache/src/index.tsx

Line 97 in c4ffc42

private download(cache: CacheEntry) {

i create a pr at #104 to enhance the lib.

Imho it is useless to handle local files in a component that you pulled in to handle cache... instead that should be a simple new component that judges to use default Image or CachedImage when remote url!
