Support cloud-native formats

[lrntct]

This would open the door to interesting uses in cloud computing.

Raster

For raster data, zarr/icechunk seems to be the obvious choice.
The advantage of Icechunk over pure zarr is transactional storage and versioning.

Vector

File-based storage like geoparquet might be an option, but a new file will need to be created at every write, and keeping track of naming might be a burden.

Another option might be ducklake, together with sqlite or duckDB. Geospatial data support is coming.
