New notebook showing how to use the output of the SPHEREx spectrophotometry tool

[troyraen]

The spectrophotometry tool extracts spectra from SPHEREx Spectral Images using forced photometry. The tool is here: https://irsa.ipac.caltech.edu/applications/spherex/tool-spectrophotometry. We should create a notebook that shows how to use the output. The GUI has a lot of visualization features but ultimately can't do the kinds of measurements that scientists need to write papers. Scientists will need to load the spectra in python (or something else) in order to do that.

We'll need to run the tool and download a file of output to feed in to the notebook. We plan to store that file at IRSA. Will update here when I know a specific location.

We especially want the notebook to highlight how to deal with the flags. The tool's help pages are being updated with info about the flags that may be helpful. A draft of those docs is here: https://irsatest.ipac.caltech.edu/onlinehelp/spherex/#sp.explorebitflags (requires VPN). I'll update the link once the docs are released.

Without an API, I think it is strange to take the output from the website and then feed that into a notebook. I would recommend we wait until the whole process can be done in python. Then this pythonic Spherex spectra can be added to the spectroscopy notebook on fornax-demo-notebooks, or I suppose a standalone could be added to this repo.

It's not strange to take this output and feed it into python code -- that's exactly what users are doing already. We want to release this notebook soon because the output is confusing and we're getting a lot of helpdesk questions about it, especially the flags. We have a plan to provide a sample file that can be used as input for this notebook. I'll add that info to the description.
