Improve get photos logic per Jared Sumner's solution

[guy-shahine]

Summary

We're facing slow performance speed when loading photos. Jared Sumner provided a solution that's explained in more details in #138 and other related issues are #110 and #168

NOTE: CameraRollExample doesn't work in Xcode 11+ because it requires an upgrade of React Native.

Test Plan

Since it's an improvement, I ran the existing tests and got no failures.

What's required for testing (prerequisites)?

1. Run CameraRollExample project
2. Accept access to photo albums
3. Observe the images load speed

What are the steps to reproduce (after prerequisites)?

Compatibility

OS	Implemented
iOS	✅
Android	N/A

Checklist

• I have tested this on a device and a simulator
• I added the documentation in README.md
• I updated the typed files (TS and Flow)
• I added a sample use of the API in the example project (example/App.js)

Quadruple pump this.

Yes please. I quintuple pump this

@guy-shahine why did you close the pr?

[guy-shahine]

@pribeh multiple reasons:
a) The package is still wired with an old structure and versions that prevents it from compiling with latest xcode
b) The tests passed but then I discovered a bug in Jared's code where a variable name was missing so tests are unreliable
c) I managed to get the example project to run in simulator but can't run on device (it requires an older iOS version that I don't have available)
d) No feedback, follow up or engagement from the maintainers

@guy-shahine thanks for sharing and your effort to implement this – I understand

@guy-shahine Have we got any solution for thumbnail of images to make it more faster?

[guy-shahine]

@tvpranav We couldn't solve it using this library so we changed our logic to use a different library that invokes the native photo picker.

Could you please tell me the library you are using? We are trying to implement a gallery but it's impossible on iOS since the memory leak and the slow performance
