ReactionPushEmojiFactory 6.45.2 API

```
public interface ReactionPushEmojiFactory

                    
```
Factory that creates emojis to be displayed in the push notifications delivered for message reactions. Example:
```
class CustomPushEmojiFactory : ReactionPushEmojiFactory {

  override fun emojiCode(type: String): String? {
      return when (type) {
        "like" -> "👍"
        "love" -> null
        else -> null
      }
  }
}
```
With the above implementation, a "like" reaction will show a thumbs up emoji in the push notification: Reacted 👍 to "Your message".
A "love" reaction will show the reaction type as text instead of an emoji: Reacted :love: to "Your message".
Important: To use this feature, you must migrate you project to use Push V3 in the Stream Dashboard.
