Crash on setting values on databinding instance when Referenced Assets change on iOS

[bassrock]

Description

When running on iOS setting both a boolean property that is in a view model, and referenced assets, the app will crash when both of those types of properties are set via Button click. However if you only set one, there is no crash. This code does work however in React Native on Android.

It looks like the crash is an EXEC_BAD_ACCESS on the following line https://github.com/rive-app/rive-react-native/blob/main/ios/RiveReactNativeView.swift#L678

Expected behavior

I'd expect the app to not crash and set the properties

Looking at this it seems to be on all set value types. Adding in the rive-ios source files its a BAD_ACCESS on the following.

It does look like its actually the following lines that cause this crash to start to occur:

        if referencedKeys != cachedKeys {
            requiresLocalResourceReconfigure = true
            return
        }

My best guess as I go through the code, is that the reloading of the whole file invalidates the current databinding instance.

Upon much deeper digging, the issue appears to be that when you add in new Referenced Asset keys, the entire Rive View is recreated which makes the existing data-bound instance invalid.
