Water Wheel animation improvement

[PusshPop]

Preliminary checks

• I've checked that there aren't other open issues on the same topic.

Describe the problem requiring a solution

The animation of the spokes and river of the water wheel/mill are 2 frames which can give the impression the wheel is going back and forth instead of round and round.

(this gif is 6 frames)

Describe the possible solution

Currently the animation consists of 6 frames. The spokes and the river are 2 frames. The outer and inner wheel (where the water is scooped up) and the water falling down is 3 frames, hence 6 frames total.
Adding images to change the spokes and the river in the 2nd and 3rd frames will turn this into a 3 frame animation cycle. It will also slow down the speed of the spokes so that it matches the speed of the wheel a bit more.
