initial add of STAC support

[flynnplatt]

Purpose

• Adds support for STAC Catalog/Collection/Item GeoJSON

Proposed Changes

• [ADD] New vector layer prefix: stac, stac-catalog, stac-collection, stac-item
• [CHANGE] Layer config ingestion to pre-process a STAC catalog/collection/item into header/vector layers
• [ADD] Automatic parsing of STAC assets for download links

@tariqksoliman We had previously discussed using this PR as an opportunity to add a dropdown to the Vector layer config that would perform the duties of the URL prefix, however I couldn't see a clean way to implement that without fully deprecating the URL prefix and that seemed like a bigger change than necessary at this point.

@flynnplatt Okay, no worries and no need to implement it in this PR then.

I tried the following vector layer URLs:

• stac:https://cmr.earthdata.nasa.gov/stac/ORNL_CLOUD/collections/AVIRIS-Classic_L1B_Radiance_2155_1/items
  • Works!
• stac:https://cmr.earthdata.nasa.gov/stac/ORNL_CLOUD/collections/AVIRIS-Classic_L1B_Radiance_2155_1
  • Gives me a header in the LayersTool but has no layers underneath it
• stac:https://cmr.earthdata.nasa.gov/stac/ORNL_CLOUD
  • Takes a while to query and then gives me a bunch of layer headers with no other layers beneath them

LGTM now!

@tariqksoliman sorry for the re-review request but I ended up changing the implementation of fetching through a STAC tree to enable parallel fetches but that meant that I had to make a string of functions async. I think I did it right but I'm not sure if you have a good regression test to double-check that I didn't introduce some bug in the initial load.

The change I made makes using stac:https://cmr.earthdata.nasa.gov/stac/ORNL_CLOUD much faster to load

LGTM and don't see any issue with parseConfig being await/asynced

Thanks!
