Added `-e` / `--env` parameter to `launch-cluster.sh` to pass environment variables to the container.
Added an experimental build option, optimized for DGX Spark and gpt-oss models by [Christopher Owen](https://github.com/christopherowen/spark-vllm-mxfp4-docker/blob/main/Dockerfile).
It is currently the fastest way to run GPT-OSS on DGX Spark, achieving 60 t/s on a single Spark. It's currently not working in a cluster configuration.

To use this build, first build the container with `--exp-mxfp4` flag. I recommend using a separate label as it is currently not recommended to use this build for models other than gpt-oss:
