Make expo-crypto an optional dependency

[jaredmixpanel]

Fix for #291

[Copilot]

Pull Request Overview

This PR makes the expo-crypto dependency optional to address issue #291 by shifting its management in package.json and adjusting the device ID generation logic accordingly.

• Moves expo-crypto from mandatory to optionalDependencies in package.json.
• Modifies mixpanel-persistent.js to dynamically require expo-crypto with a fallback to uuid.v4() when generating a device ID.
• Removes .vscode/settings.json.

Leaving this here in case this helps anyone else.

On react-native 0.76 and expo 52 I got the following error, solved by downgrading to mixpanel-react-native@3.0.9 to avoid the expo-crypto module.

@sseppola v3.1.2 is released which removes expo-crypto and adds react-native-get-random-values which should fix the original problem in Expo apps without creating a dependency on any Expo modules.
