v1.3.0

New Features

• The new FitTrace class (see "API Changes" below) introduces the
  ability to take a polynomial trace of an image [#128]

API Changes

• Renamed KosmosTrace as FitTrace, a conglomerate class for traces that
  are fit to images instead of predetermined [#128]

• The default number of bins for FitTrace is now its associated image's
  number of dispersion pixels instead of 20. Its default peak_method is
  now 'max' [#128]

• All operations now accept Spectrum1D and Quantity-type images. All
  accepted image types are now processed internally as Spectrum1D objects
  [#144, #154]

• All operations' image attributes are now coerced Spectrum1D
  objects [#144, #154]

• HorneExtract can now handle non-flat traces [#148]

Bug Fixes

• Fixed passing a single Trace object to Background [#146]

• Moved away from creating image masks with numpy's mask_invalid()
  function after change to upstream API. This will make specreduce
  be compatible with numpy 1.24 or later. [#155]
