* @brief Launches a ray for raycasting to determine the distance to the first wall.

* This function calculates the distance of a ray cast in a specified angle

*
* @param info A pointer to the `t_info` structure containing the map and other relevant data.
* @param angle The angle of the ray being cast, in radians.
*
* @return The distance from the starting position to the first wall hit.
* If no wall is hit within `MAX_RANGE`, the function returns `MAX_RANGE`.
