Add new type of room: maze room

[ilja615]

A large room with a hedge maze.

• The room must have a new method in the World-class: private Room makeMazeRoom(Direction dir){}
• For this room method, the MUSHROOM room has to be copied and modified.
• The method must be called within the randomizer switch in line ±207 of the world class

About the room:

• The room should be bigger than normal, like maybe around 8x8 - 11x11
• Coordinates in the room should be included in the noObstacleZone.add(coord); to ensure no extra obstacles to randomly generate inside the maze
• The room should have a maze of bushes! fun!
