ENH: Ingest STAC Items as input (instead of path)

[remi-braun]

Next step toward STAC compatibility would be to handle ingestion of a STAC Item instead of a Path in the Reader().open function.

There is a lot of STAC formats out there.
It won't be possible to handle them all:

• Microsoft Planetary Computer:

  • Sentinel-2 L2A
  • Landsat L2
  • Landsat L1
  • S1-RTC (needs Handle Sentinel-1 RTC product #112)
  • ❌HLS (Not yet available)
  • ❌S1 SLC (Not yet possible as SNAP doesn't handle other format than SAFE)
  • ❌S1 GRD (Not yet possible as SNAP doesn't handle other format than SAFE)

• Element84

  • S2 L2A COGS
  • S2 L1C
  • Landsat L2
  • ❌S1 GRD (Not yet possible as SNAP doesn't handle other format than SAFE)

• Others

  • Products: Maxar, Umbra, Capella... See https://stacindex.org/catalogs
  • Providers: Astraea...
