Feature request: allow customization of Firework effect damage

[Phil25]

72 overviews settings to be added to use legacy effects, including Firework.

I’ll change the suggested explode setting to damage and default to explode the player if damage would kill them. That be ok?

[Tiagoquix]

Sure. It would be cool to the possibility of a value of -1 for damage so it would always kill the player regardless of buddha/godmode/current health points (basically the same as the legacy Smite idea).
