Photosynthesis Game Insert - Remix

Remix of [froggy2288](https://www.thingiverse.com/froggy2288)'s fab [Photosynthesis Game Insert](https://www.thingiverse.com/thing:2853309). I wanted to:
1. Separate out the trees by size,
2. Give all of the component containers somewhere to sit without moving around, and
3. Have somewhere to store the sun segment.

So I've just separated out each player's sections into three - one for each tree size, added holders for each player's component containers, and added a side tray that takes the player-one marker and the sun segment.
