feat: Add Arduino code for position tracking

The code changes include adding a new Arduino sketch for position tracking. The sketch is located at `code/arduino/Position-tracking/Position-tracking.ino`. Additionally, a new class `PositionSensor` is added with its corresponding header and implementation files. This class handles the position sensor functionality and includes methods for initialization and measurement.

The commit message suggests that the changes are a new feature addition related to position tracking in the Arduino code.
