Indicative Pitch

Edit: WARNING! THIS WILL CRASH ON 1.21.2+! Use version 1.1.1 instead for those versions.

Added another mixin, as shown below, to change the pitch of the sound when the block actually breaks. 

@Mixin(LevelRenderer.class)
public class LevelRendererMixin {

    @ModifyExpressionValue(at = @At(value = "INVOKE", target = "Lnet/minecraft/world/level/block/SoundType;getPitch()F"), method = "levelEvent")
    private float modifyPitch(float original) {
        float returnValue = 2.0f * original;
        // System.out.println("Returning " + returnValue);
        return returnValue;
    }

}
