Support GeoParquet as Data Source/Exporter with S3 Integration

[yharby]

Is your feature request related to a problem? Please describe.

GeoParquet is increasingly used for efficient geospatial data storage, and S3 (e.g., Overture Maps’ public buckets) is a common data storage solution. Hootenanny lacks support for GeoParquet and cannot directly access S3 storage, making workflows cumbersome and less efficient.

Describe the solution you'd like

1. GeoParquet Support:

• Import GeoParquet files with geospatial metadata (geometry, CRS).
• Export processed data to GeoParquet format.

2. S3 Integration:

• Read/write GeoParquet directly from/to S3-compatible storage, including Overture Maps’ public buckets and private buckets (with credentials).

Describe alternatives you've considered

• Manual downloading/conversion of GeoParquet files from S3 to supported formats, or using external tools like GDAL. These workflows are inefficient and add complexity.

Thank you!
