Make `navigator` perform ArUco search

[onkoe]

Goal

Utilize the aruco::aruco_node to perform ArUco search algorithm using long-running action.

Description

The aruco_node is mostly finished, but we aren't using it yet!

To do so, we need to use its action in the navigator::navigator_node.

Checklist

• Remove everything from src/navigator/navigator_node/search.py
• Open up src/navigator/navigator_node/main.py.
• When it's time to find an ArUco marker, start an action client with the aruco::aruco_node. Then, call self.search(), storing the resulting Task in the NavigatorNode class, as needed.
• Implement a search algorithm
  • This can be EXTREMELY basic for now. Just do small circles.
  • Continue the search until you find the marker!
    • That means aborting the Task (stopping the async def search(self)) whenever the target marker is within the returned FindArucoWithPose_Feedback.marker_ids field (class attribute).
