Add preferred citation

[dlebauer]

Goal: Make it easy for users cite AZMet data.

First step: provide a preferred citation in text on the main page.

Eventually:

• Provide a doi
• Regularly publish new versions to, e.g., UA's ReDATA (figshare) or Zenodo. Annually might suffice. Might be worth contacting library for suggestions.

By 'main page', do you @dlebauer mean like this (citation at bottom of page): https://staging.azmet.arizona.edu/past-data?

[dlebauer]

Sorry for being ambiguous! I was referring to the shiny app https://viz.datascience.arizona.edu/azmet/azmet-data-preview-and-download/
