RNVideoTrimmer, RNTrimmerViewManager requires main queue setup

[osdiab]

Current Behavior

Yellow warnings when running the app, saying:

Module RNTrimmerViewManager requires main queue setup since it overrides `init` but doesn't implement `requiresMainQueueSetup`. In a future release React Native will default to initializing all native modules on a background thread unless explicitly opted-out of.

Your Environment

Shows up on iOS (haven't checked android), package.json relevant dependency versions:

{
  "dependencies": {
    "react": "16.4.1",
    "react-native": "^0.56.0",
    "react-native-video-processing": "shahen94/react-native-video-processing"
  },
  "devDependencies": {
    "babel-preset-react-native": "^5.0.2"
  }
}

Node 9.3.0 react-native-video-processing version in yarn.lock: e7262a3fec73e26b3a77aac83eae278a130a0773, yarn list shows that it's @1.7.1

I've just fixed this.

1) RNVideoTrimmer.swift

@objc(RNVideoTrimmer)
class RNVideoTrimmer: NSObject {
   ...
+   @objc class func requiresMainQueueSetup() -> Bool {
+      return true
+   }
}

2) RNTrimmerViewManager.swift

@objc(RNTrimmerViewManager)
class RNTrimmerViewManager: RCTViewManager {
    ....
+    override class func requiresMainQueueSetup() -> Bool {
+      return true
+    }
}

3) Clean and Run

Hope this helps :)
