spectral_utils error message

[cdeline]

Error message on a new py3.13 environment. All tests in test_spectra.py are failing, but everything else passes. If this is an environment issue, then the error message needs to be made more informative.

      return (spectral_alb, spectral_dni, spectral_dhi, weighted_alb)

E UnboundLocalError: cannot access local variable 'spectral_alb' where it is not associated with a value
