Applying blasé to spectra from new instruments, e.g. VLT ESPRESSO

[gully]

In the paper, we demonstrate blasé on IGRINS and HPF spectra, using muler to do the pre-processing. There has been some interest in applying blasé to spectra from other instruments, which should be straightforward, since muler is not a prerequisite to using blasé.

I propose we make a tutorial that shows an end-to-end worked example, which would have these pre-processing steps:

1. Read in a .csv file of wavelength, flux, error
2. Pack that into a Specutils Spectrum1D object
3. Retrieve a PHOENIX template for that target (with or without gollum, probably without for simplicity)
4. Access the .bin_edges attribute of the Spectrum1D object, for the resampling step
5. Proceed identically as in existing tutorials
