Returning an already serialised object from command

[AudriusButkevicius]

I already have a Vec that contains the json payload I want to return. Can I somehow tell Tauri not to reserialize that? I guess I can have a wrapper struct that implements the serialise crate which does nothing, but I hoped there is a better way to do this?

Also, what about cases where the amount of data I'm sending is quite big? Getting access to the response writer would be quite useful not having to have the massive allocation, and just stream the response to the browser.

I see the ipc v2 has landed, however there isn't much docs on how to use that.
