Remove useLocalImages as it bloats the lib

[pederjohnsen]

This was removed previously but due to some bug in React Native/fresco it was added back in: #77

We could consider using <FastImage /> instead of <Image /> if bug is still present 🤔

This can now be done as Fresco snd React Native have been updated:
facebook/react-native#45078 (comment)

Alrighty, last update for a little while (at least until this gets packaged up into the next release):

• Add resizeMethod type 'none' to disable downsampling on Android #46866 was merged and adds a new resizeMethod called none. This maps to the NEVER downsample mode in Fresco on a per-image basis.
• I've added documentation regarding this new resize method to https://reactnative.dev/docs/next/image#resizemethod-android with a brief disclaimer about what I've shared here: it can be a footgun that causes runtime exceptions
• Add example of different resize methods #46873 adds a showcase of each of the four resizeMethod to the RNTester app. I'm setting up tests to run against these images to ensure that downsampling is always correctly turned off when this prop is supplied

You can follow along with the release status of this change by checking out the tags associated with 6202319 (right now there are none). When you pick up the change in a new release, it should be as simple as using it like this:

<Image 
  source={require('./assets/my-large-image.png')} 
  resizeMethod="none" 
/>
