Locator Maps Show a 3D Model Of Players Head, Capes, Elytra and Armor

When holding a locator map, you can see a full 3d render of other players heads, and what direction they are currently looking.

If the player is wearing a cape, you can also see the backside of it represented on the map.

There is also a white square behind the players head.

How to reproduce:
1. Get two players near each other
2. Open a locator map, and move away from the other player so their colored icon goes away
3. You should see the colored icon turn into a render of their skins head, their cape, armor/shield
