EmojiLayer class

The EmojiLayer widget allows users to position, scale, and rotate an emoji overlay on an image. Tapping on the emoji opens a customization dialog, where users can adjust properties like the text or size through EmojiLayerDialog. The layerData contains properties of the emoji, including position, size, and rotation. It supports both light and dark themes, allowing for adaptive dialog background colors. The onUpdate callback is invoked when modifications occur, providing additional control for external actions on update.
