Added raster geopackage checker

[ywkim312]

This PR will check if the geopackage file contains raster layer or no vector date layer.
To test, please use attached geopackage file

Scenario1: Uploading the raster based geopackage file

1. download attached geopackages.zip file and unzip it. Should be two files, one named guid_test.gpkg, and the other is landcover.gpkg
2. create a dataset using the following json (the content doesn't matter too much because it is test. Only important one is the format, that should be geopackage)
   {"format": "geopackage", "title": "test-delete", "description": "delete me", "dataType": "incore:addressPoints"}
3. attached the geopackage file to the dataset using the landcover.gpkg file (raster geopackage)
4. if you use landocver.gpkg, then you should see the error message saying, it doesn't contain any vector layer or it contains the raster
5. if you get error in step 3 above, try to attach the guid_test.gpkg (vector data). This should work without any error.
6. Remove the dataset you created in step 1.
