[Feature Request] Rich Notifications support for iOS

[Casuallynoted]

I’d like to see React Native fully support rich notifications on iOS. From what I can tell based on what the Discord team has said, React Native doesn’t support it and therefore apps made in it can’t have the feature.

Is this something that can be implemented as a native module? If not, and you believe a change needs to be made to the core library to allow the functionality, please start a discussion in http://github.com/react-native-community/discussions-and-proposals/.
