docs: Passed as keyword arguments to [`numpy.genfromtxt`][1]
          when called by `scipy_data_fitting.Data.load_error`.
  
          Even if defined here, the `usecols` value will always be reset based
          on `scipy_data_fitting.Data.error_columns` before being passed to [`numpy.genfromtxt`][1].
  
          If not set, this defaults to a copy of
          `scipy_data_fitting.Data.genfromtxt_args` on first access.
