Add Stormburst calc for Exploding Orb Damage (#9530)

Adds the component of the skill that deals explosive damage in an area after you stop channeling.
Tested the mechanic in-game to make sure the damage multipliers are correct
When you have less than 0.8s duration the skill does not gain any damage
