extent in STAC result metadata should be lat lon

[jdries]

For a job (j-f4a4a6605c7c4b8d8ec8e79a2dbd408e) that specifies the bounding box in EPSG:3035, I get the metadata below in job results. I believe stac extents are always in EPSG:4326. The extent in asset crs can go in proj:bbox (but the filter_bbox crs is not necessarily asset crs...)

"extent": {
    "spatial": {
      "bbox": [
        [
          2780000.0,
          1820000.0,
          2800000.0,
          1840000.0
        ]
      ]
    },

This line of code seems to ignore crs entirely:

openeo-geopyspark-driver/openeogeotrellis/deploy/batch_job.py

Line 100 in d7aa375

bbox = [spatial_extent[b] for b in ["west", "south", "east", "north"]]

That would need to be changed...
