Poison Kills

With Poison Kills in your datapacks, you need to be very afraid of getting poisoned, as it will no longer leave you alive with half a heart, it will be merciless and kill you and any other entity that might have gotten poisoned!

This datapack will make it so that any entity that gets poisoned and is low enough on health, will ultimately die if not cured in time.

Thanks to Up and ChiefArug on Discord for helping me debug and get this working!
