Implement clicks for tiles - Zappy GUI

[Thomaltarix]

Is your feature request related to a problem? Please describe.
When looking at the map during a Zappy Game, you should be able to click onto the map tiles to see their content.
Each Tile contains:

• Food
• linemate
• deraumere
• sibur
• mendiane
• phiras
• thystame
• Player Number
• Egg number

Describe the solution you'd like
To do so, i initially need to implement the hitboxes of the tiles.
Then, i'll need to implement the click onto those tiles.

Additional context
Btw, the HUD display (when a tile is clicked) will be setup in this issue: #90
