Advanced animation for 3D models in Pomodoro timers

[yevhenii-nadtochii]

This issue suggests updating the used animations for timers. As for now, 3D models are just rotating, not taking into account the remained time.

The suggested animations are the following:

1. A remaining piece of tomato (cut) according to the amount of time remaining. Duration is 25 min. Like this.
2. A semi-transparent coffee cup of espresso, with an amount of liquid proportional to the remaining time. Duration is 5 min. Like this.
3. A semi-transparent tall cup of cappuccino, again, with an amount of drink proportional to the remaining time. Duration is 15 min. Like this.

Each model should have a transparent background and the running code should be written with three.js.

@yevhenii-nadtochii Isn't it completed already?

@vladimir-ikryanov The implemented animation is much simpler compared to the ones described in the issue. I've updated the issue description and added idea label.
