Export EmojiAvatar component and emojiAvatarForAddress utility

[drichelson]

The EmojiAvatar component and emojiAvatarForAddress utility function are currently internal and not exported from the main package, making it impossible to reuse RainbowKit's avatar logic in custom components.

Use Case

I want to display consistent emoji avatars outside of RainbowKit's built-in components (e.g., in a user list, profile cards, etc.) using the same address-to-emoji mapping that RainbowKit uses internally.

Proposed Solution

Export the following from the main package:

  export { EmojiAvatar } from './components/Avatar/EmojiAvatar';
  export { emojiAvatarForAddress } from './components/Avatar/emojiAvatarForAddress';

Current Workaround

Currently, the only way to access this functionality is to copy the implementation or access it through custom avatar components via AvatarComponent, which doesn't provide the standalone utility function.
