class_docstr: Determines if a datetime falls during working hours on a 24-hour clock. Can configure start_hour and end_hour.
  
  Args:
      start_hour (int): Start hour of workday. Must adhere to 24-hour clock. Default is 8 (8am).
      end_hour (int): End hour of workday. Must adhere to 24-hour clock. Default is 18 (6pm).
  
  Examples:
      >>> import numpy as np
      >>> from datetime import datetime
      >>> dates = [datetime(2022, 6, 21, 16, 3, 3),
      ...          datetime(2019, 1, 3, 4, 4, 4),
      ...          datetime(2022, 1, 1, 12, 1, 2),
      ...          np.nan]
      >>> is_working_hour = IsWorkingHours()
      >>> is_working_hour(dates).tolist()
      [True, False, True, False]
      >>> is_working_hour = IsWorkingHours(15, 17)
      >>> is_working_hour(dates).tolist()
      [True, False, False, False]
