Limit camera movement to in game world

[BenKellySoftware]

Feature description
We want to limit the movement of the camera so the player can't see the edges of the environment design

Acceptance criteria/subtasks

• Keep the movement free when going out into the water so we can still have that fun 'nothings here' bit. Maybe make the limit a cone shape so they can't just go around the island either.
• Prevent the user from moving the camera past the mountain ranges in the playable area of the game
