Enhance Fields of the World dataset to be an exemplar Source Cooperative dataset

[PowerChell]

Once the ASU dataset is hosted on Source Cooperative (#2), make this dataset an exemplar fiboa dataset for public example.

• Potentially create fiboa-cli converter
• Potentially create missing extensions
• Validate data
• Publish to Source Coop with great readme explaining what it’s about and how to use it
  • add PMTiles
  • add STAC Collection
  • potentially add GeoJSON examples

We've made quite a bit of progress on this. Tagging @hannah-rae @aninda-ghosh @eddiechoi00 so they are aware of this issue.
