Add an explosion_power field to sulfur cubes

I think it would be great if sulfur cubes had a way to change the strength of their explosion power when they have a tnt inside them, similar to the ExplosionRadius field that creepers have, or the explosion_power field that tnt entities have. It seems strange that you can currently change the Size of sulfur cubes with commands, but there's no way to make it so that the explosions they create scale with it, especially when the previously mentioned mobs already have such options.
