Challenge Timer

Challenge Timer datapack by mzxciap.
NOTE: THIS IS NOT A CHALLENGE DATAPACK ON ITS OWN, IT IS MERELY SUPPLEMENTARY TO OTHER CHALLENGE DATAPACKS.
This datapack gives you a timer in your action bar.
It is intended for use in a challenge to see how long you stay alive for.
This datapack is multiplayer and survival/creative friendly.
It uses the actionbar and does not work with other datapacks that use the actionbar.
The timer starts when you spawn, stops when you die, and resets when you respawn.
When you die, it announces your time in chat.
The datapack namespace is "timer:".
The timer only displays minutes and seconds (no hours).
The score/tag namespace is "tim_".
