v1.6.0

Bug Fixes

• When all-zero bin encountered in fit_trace with peak_method=gaussian, the bin peak
  will be set to NaN in this case to work better with DogBoxLSQFitter. [#257]
• Reverted the changes to background.Background.bgk_spectrum introduced in 1.5.0 [#266].

Other changes

• Compatibility with specutils 2.0. [#260]
• Set Python 3.11 as the minimum supported Python version and added test support
  for Python 3.13. [#271]
• Changed the statistic parameter in utils.measure_cross_dispersion_profile to accept
  either median or average instead of median or mean. [#258]
