      Check whether the dtype should be converted to int64.
  
      Dtype "needs" such a conversion if the dtype is of a datetime-like dtype
  
      Parameters
      ----------
      dtype : np.dtype, ExtensionDtype, or None
  
      Returns
      -------
      boolean
          Whether or not the dtype should be converted to int64.
  
      Examples
      --------
      >>> needs_i8_conversion(str)
      False
      >>> needs_i8_conversion(np.int64)
      False
      >>> needs_i8_conversion(np.datetime64)
