Add support for streaming data

[KumoLiu]

Adding support for streaming data to enhance the real-time processing capabilities. This feature would enable our platform to handle continuous flows of data, which would open up new use cases and improve responsiveness in data-driven applications.

I will mention here as well the gist demonstrating bundle inference with GStreamer. This differs a lot from how MONAIStream operated by adapting an existing bundle rather than defining components separately, and doesn't use DeepStream. I think this is useful as a contrasting concept on how to revive this form of stream support.
