Figure out data access for ZTF images

[jkrick]

Is ZTF accessible via SIA v1? is it something else? How does one access ZTF images? Is the COSMOS tutorial helpful in figuring this out?

• make a tutorial showing this for irsa-tutorials
• suggest edits to the SIA v1 access page https://irsa.ipac.caltech.edu/ibe/sia_v1.html
• suggest edits to this general data access page: https://irsa.ipac.caltech.edu/docs/program_interface/api_images.html
