Logs performance metrics for a single step of the robot control loop.
This function formats and prints a single line of log information, including episode/frame counters,
total loop time (dt), and detailed timings for various robot and camera operations. It can also
highlight performance drops in yellow if the actual FPS is lower than the target FPS.
Args:
robot: The `Robot` instance, used to access its internal logs for detailed timings.
dt_s: The total duration of the control loop step in seconds.
episode_index: The index of the current episode.
frame_index: The index of the current frame within the episode.
fps: The target frames per second, used to check for performance degradation.
