Check for common errors in spatial_extent

[EmileSonneveld]

Users often type errors in spatial extent. This often gives errors, but sometimes very obscure ones.

For example:
'spatial_extent': {'west': [0], 'south': 60.11, 'east': 25.24, 'north': 60.35, 'crs': 'EPSG:4326'},
'spatial_extent': [1,2,3,4],

The following already gives an error:
"spatial_extent": {"east": 4, "north": 51.22, "south": 51.215, "west": 5}, -> geotrellis.vector.ExtentRangeError: Invalid Extent: xmin must be less than xmax (xmin=5.07, xmax=4.08)

Maybe we can also catch UTM coordinates while no CRS is specified.

User example that could be caught by this:

        "spatial_extent": {
          "west": 4329317.717132108,
          "east": 4330615.2810456185,
          "north": 3005295.0854642093,
          "south": 3003997.791438847
        },
