Implementation of data exchange mechanisms between robot and supervisor using Serial Webots drivers

[akrambzeo]

Main functions:

Initialization of the serial communication:

Initialize the serial driver in the robot and in the supervisor.

Sensor data transmission:

Sensor data is sent from the robot to the supervisor, and the supervisor receives the data.

Motor control:

The Supervisor sends the specified motor control data to the robot.
The robot receives the motor control data and updates the motor speeds accordingly.

Reset Logic for Loss of Line Tracking:

Monitor sensor data for loss of line tracking.
Initialize the robot's position and orientation after a fixed number of steps without line detection.
Reset the robot to the standby state without recalibrating the motors and sensors.

Training or driving mode:

The mode (training or driving) is selected by pressing a button.
If no button is pressed within a specified time, the robot will default to the training mode.
Training or driving will not begin until the start/stop line is crossed.

Did not review content but structure and integrity of other apps.

• All files under the path lib/APPReinforcementLearning/ and lib/HALReinforcementLearning/should be contained in a src folder. Check the structure in other apps.

Looks good to me. @hoeftjch should make the final lreview and approval before merging.
Edit: found some more stuff

looks good to me now. Architecture changes in RL_Supervisor will likely be necessary for next updates.
