Feature request: support for streaming

[hoskin]

Cog supports streaming output. Would be amazing if this was simple to use with RunPod.

Example cog worker with streaming: https://github.com/LagPixelLOL/cog-exllama
Cog streaming docs: https://github.com/replicate/cog/blob/main/docs/python.md#streaming-output

Thank you for the great work!
