Explosion sound should be different for each size of dynamite

The sound effect of a single stick of dynamite exploding is as loud as a triple dynamite.

I would find it more satisfying to hear a "weak" explosion for the single stick, and a "strong" explosion for the triple stick.

I think the current sfx in version 1.0 is good for a double. Weaker version could have less bass, stronger more bass (since you go deeper in the ground)
