in VisionCamera v1 & v2 there were two ObjC macros that were helping
in creation/registration of Frame Processors, but these were removed with
v3
This PR reintroduces such macros, which will not only make FP development
easier, but also it will also fix issues people had with registration of
Swift Frame Processors (+load vs +initialize issues)
Docs were also updated to reflect that the macros should be used to
correctly initialize and register ObjC/Swift Frame Processors
Moves everything Camera related into `core/` / `Core/` so that it is better encapsulated from React Native.
Benefits:
1. Code is much better organized. Should be easier for collaborators now, and cleaner codebase for me.
2. Locking is fully atomically as you can now only configure the session through a lock/Mutex which is batch-overridable
* On iOS, this makes Camera startup time **MUCH** faster, I measured speedups from **1.5 seconds** to only **240 milliseconds** since we only lock/commit once! 🚀
* On Android, this fixes a few out-of-sync/concurrency issues like "Capture Request contains unconfigured Input/Output Surface!" since it is now a single lock-operation! 💪
3. It is easier to integrate VisionCamera outside of React Native (e.g. Native iOS Apps, NativeScript, Flutter, etc)
With this PR, VisionCamera V3 is up to **7x** faster than V2
