[Feature request] Multiple documents in stream

[Gabriel de Perthuis]

At least JSON and YAML support having multiple objects/documents in a stream, YAML separates them with '---' on a separate line, and JSON (jq for example) with a newline.

I would find this conversion useful.

Thank you!

Sorry, but I am not interested in this feature. I'll merge it if someone contributes a good-quality implementation with tests.
