AI continuous with logger

  1'''
  2AI - AI_continuous_with_logger.py with asynchronous mode.
  3
  4This example demonstrates the process of obtaining AI data in continuous mode with 8 channels from WifiDAQE3A.
  5Then, save data into CSV file.
  6
  7To begin with, it demonstrates the steps to open the AI and configure the AI parameters.
  8Next, it outlines the procedure for reading and saving the streaming AI data.
  9Finally, it concludes by explaining how to close the AI.
