Terrain & Structures collisions / entities movements in the world

[Sceat]

We need to find an efficient algorithm/system for collisions, which would include:

• clean movements when going up a single block
• clean movements for entities and pets
• collisions against 2 block high and trees/structures
• collisions for the camera (near the player only) to prevent the camera from going under the map

tbc with the new @aresrpg/aresrpg-world, collisions might change

camera collisions works out of the box with https://github.com/yomotsu/camera-controls but it might be inneficient especially because it only works with threejs meshes
