Add support for objective-c

[adamkoch]

My expo project still outputs the iOS directory using objective-c. Looking at the iOS guide for RN (non-expo) I think it should still work fine by adding CodePush to the objective-c files?

I tested by patching locally and it seemed to work fine. But not sure if there was some other reason you only had Swift support.

@adamkoch what is your SDK version? can you share your patch via PR?

I am using expo + react-native-tvos:

"expo": "^52.0.47",
"react-native": "npm:react-native-tvos@~0.76.9-0",
"@revopush/expo-code-push-plugin": "^1.0.1",
"@revopush/react-native-code-push": "^1.4.0",

Here is the patch I'm using:
@revopush+expo-code-push-plugin+1.0.1.patch

After testing a bit more, I am running into a few oddities though with fonts loading (iOS) and resources loading (Android) after applying a patch. I'm not sure if it's related to this or something to do with expo. Basically after patch those resources are not loading correctly so images/fonts are missing. Even though I see all the resources in the patch themselves. What's strange is it doesn't seem to always happen, sometimes it works fine.

On iOS the crash looks like this (fails to load a font):

Error: Calling the 'loadAsync' function has failed
→ Caused by: Registering 'material' font failed with message: 'Font registration was unsuccessful.'. CTFontManagerError code: 101

On Android it looks like this (fails to load an expo image asset):

Error: Call to function 'ExpoAsset.downloadAsync' has been rejected.

Update: the errors with iOS and Android appear unrelated to the PR.

iOS - was a metro bundler config (my fault)
Android - I use some SVGs with expo-image which don't appear to load after patch. I'm guessing expo does some conversion in the full build but not on the metro export. Not sure.
