Add name tag timers above loot chests

Loot chests should have a visual indicator above them displaying the time left remaining before a loot chest can be opened, or if it is ready to be opened, the name tag should be "READY"

For simplicity's sake we'll only spawn an armor stand after the player loots the chest with a timer that destroys the armor stand on timeout
