This is needed for SustainableDevelopmentReform/csdr-cloud-spatial-app#35

  • Write compliant STAC-Geoparquet (bbox metadata etc.) with arrow geometry field.
  • Write PMTiles for ACA Reef

I am a little stuck here. I need to write the STAC-Geoparquet from arrow using stac_geoparquet.arrow.to_parquet()
I am hitting this issue apache/arrow#44696
The error I get is: ArrowKeyError: Attempted to register factory for scheme 'file' but that scheme is already registered.

I got hard errors when reading the STAC-Geoparquet files after they were written with arrow. I think we need another column called arrow_geometry that is seperate from the main binary geometry.
