Add Y coordinate to player updates

[thebuildcraft]

Hi. I am making a fabric client mod that shows the position of players as waypoints in Xaero's maps, so players can see each other from further away in game. It does this by getting the position data from Squaremap. Unfortunately, the HTTP get-request just returns the x and z coordinates. This is not an issue for the map, as it is 2D. But for my mod it is not so good, because it means I can't display the waypoints at the correct height.
