In [PR#980](#980) introduced streams into the halo exchanges. For this also `DEFAULT_STREAM`, which models the default stream and implements the [CUDA Stream Protocol](https://nvidia.github.io/cuda-python/cuda-core/latest/interoperability.html#cuda-stream-protocol). However, the original implementation identified as protocol version `1` instead of version `0`. Because of a related bug in [GHEX](ghex-org/GHEX#202) this error was hidden. This PR fixes the Python implementation and also updates GHEX.
