Add proper liquid animation

Liquid should fill the cup in correct way.
Hint: Use a transposing background with a transformed div

Alternative: Use 3DJS to create a path. Either transform it depending of the fillLevel or transpose a background as filling of the path

Another idea: useSpring reactHook
