v1.13.0

New Features

• Added SDSS-V file format readers. [#1107]

• Switched from using numpy.correlate to scipy.signal.correlate in template_correlate
  and enabled passing through the method argument. [#1114]

• Added DESI file format readers. [#1116]

• Added truncate option for resampler and template correlation extrapolation treatment. [#1121]

Bug Fixes

• SDSS reader now properly exposes the spPlate_identify and spPlate_loader functions. [#1097]

• Masks now round-trip through tabular-fits reader/write. [#1104]

• template_correlate no longer errors when used on a Spectrum1D that lacks an
  uncertainty array. [#1118]

• with_spectral_unit has been changed to with_spectral_axis_unit and actually works
  now. [#1119]

• Template correlation functions now truncate to overlapping region to avoid NaNs in normalization
  when spectrum and template have non-overlapping regions. [#1121]

• Fixed numpy error when printing a Spectrum1D object. [#1123]

Other Changes and Additions

• Made a couple small updates to developer docs. [#1110, #1112]

• Updated the format of Spectrum1D.__str__ and Spectrum1D.__repr__. [#1123]
