[Bug]: unity-sds-client error response in get_collection_data

Describe the bug

@wphyojpl :
https://github.com/unity-sds/unity-monorepo/blob/main/libs/unity-py/unity_sds_client/services/data_service.py#L73

I think this response in unity py should check the status code and throw an error accordingly for 400s and 500s.
Currently, it throws this error

KeyError                                  Traceback (most recent call last)
Cell In[15], line 4
      1 dataManager = s.client(services.DATA_SERVICE)
      2 collection_id = f"URN:NASA:UNITY:{os.environ['PROJECT']}:{os.environ['VENUE']}:QSR_10"
----> 4 cd = dataManager.get_collection_data(Collection(collection_id), limit=100)
      5 for dataset in cd:
      6     print(f'dataset name: {dataset.data_begin_time}')

File ~/.local/lib/python3.11/site-packages/unity_sds_client/services/data_service.py:75, in DataService.get_collection_data(self, collection, limit, filter, output_stac)
     73 if output_stac:
     74     return response.json()
---> 75 results = response.json()['features']
     77 for dataset in results:
     78     ds = Dataset(dataset['id'], collection.collection_id, dataset['properties']['start_datetime'], dataset['properties']['end_datetime'], dataset['properties']['created'], properties=dataset['properties'])

KeyError: 'features'

What did you expect?

catch 400 and 500 responses
