Extract 2D Spectra from Echelle

This code seems to do very well at visualizing and gaining information from 1D spectrum from Echelle spectrographs, after the 2D Echelle spectra have been extracted into a stack of 1D spectra.

I see in #11 that there is mentioned of a Spectrum1DEchelle; but that seems to be how to handle multiple 1D spectra, as oppose to extracting 2D flux vs pixels into sets of 1D spectra.

Is there are way to take the 2D Echelle spectra (photons vs pixels) with the geometric distortions and needed wavelength calibrations (from comparison spectra) to generate these 1D spectra here -- not using IRAF, which is a monstrosity.

Is there are section of this package that extracts the 1D spectra from a 2D image?
