initial citation and changelog

[scottyhq]

Addresses #15 and #151 to add GitHub Citation.cff. More detail on the fields you can have in citation.cff are here https://github.com/citation-file-format/citation-file-format/blob/main/schema-guide.md

After merging this we'll create a release linked to a zenodo DOI and then add the DOI to citation.cff

This does not address the tutorial data reproducibility discussed in #151, but at least will give us a citation for the jupyterbook website.

I did my best to find everyone on the 'team' page https://snowex-hackweek.github.io/website/team.html by name and affiliation on https://orcid.org, but some are missing.

[scottyhq]

will fill this in after creating a release, planning to use calendar naming scheme (so 2021.07.23, 2021.09.01, etc. for updated versions)

[scottyhq]

note this is a single citation for the entire book/website, rather than broken down per tutorial.

Using pip install git+https://github.com/citation-file-format/cff-converter-python.git cffconvert -f apalike (what will show up on the GitHub repo landing page the citation looks like this):
