[FEATURE] Optimize collision detection algorithm

[manucamejo]

Currently we're checking if a player collided with every obstacle in the map, we should only check with obstacles that are close to the player for collision detection and resolution

Some possible solutions may be:

• implement spatial hash grid to query close obstacles, we already have a first implementation of this in the repo in a branch called old
• Implement quad trees with the same objective as hash grids → see quad trees video https://www.youtube.com/watch?v=sC8514mf0OA
