Bounding boxes

Added rooms, slopes and objects that can be used to define rooms as well as some examples (that will be removed in the future, of course, but can stay rn imo as a demo)

Right now they are rendered as follows:

• Rooms = green wireframes
• Slopes = white wireframes
• Objects = red wireframes

Rendering is still handled in the FirstPersonController right now, will be moved though together with #8 .

Collision detection is handled in the FirstPersonController as well, but that can stay there.

Add a boolean constant for displaying wireframes so you only have to change the constant instead of changing the MeshBasicMaterial wireframe boolean for every single wireframe rendered object.
Change the movement when walking against objects to be the same sliding movement that you get when walking against walls. Should add way smoover movement in rooms with many objects.
Slopes need to be rotatable to account for stairs not always facing one direction. We can ignore that issue for now though, as we probably wont have stairs scanned at KIMS.
Elsewise the code is fine and easily expandable to account for more objects rendered! Good job!

Thanks for the review. As for the rendering being done optionally, that needs to be tackled when both features that are currently worked on are ready and can be moved to a seperate rendering class.

The QoL change of not getting stuck on objects as easily also needs to be addressed in the next sprint, as it's too small of a timeframe between that and the start of the next sprint, so we'll open a new ticket for that.
