Chunked body streaming with fine-grained control

[whatyouhide]

Hiya @sneako 👋 🙃

So I was playing around with some stuff yesterday and I ended up needing a way to take a Finch request and feed chunked body into it. This is doable with body: {:stream, stream}, but with that the control for when the body is fed into the request is in Finch's hands.

Instead, I’m looking for an API like Mint's stream_request_body (which Finch's {:stream, stream} uses). Is this doable, or has it been proposed before? Haven't had time to look into feasibility of this yet. 🙃

Hey Andrea! Sorry for the late reply, I was traveling for the second half of August. I'm back at it now.

This isn't a use case I have needed or thought much about yet, but its not something I would be against.

Maybe some pseudo code showing your ideal API could help us flesh it out a bit?
