"Fuzz" and "robot" effects not working

[ericrosenbaum]

Expected behavior

The "set effect fuzz to 100" block should cause sounds to play with a nice fuzzy distortion.

The "set effect robot to 100" block should cause sounds to play with a buzzy robotic quality.

Actual behavior

These blocks have no effect.

Steps to reproduce

Go to https://llk.github.io/scratch-gui/ and create these stacks:

clear audio effects
set effect fuzz to 100
play sound 1

clear audio effects
set effect robot to 100
play sound 1

they should play the meow sound with fuzz and robot effect applied, respectively, but they don't.
