Wildcard subs nats #1042
Description
Using nats transport there is no way to find out the reply subject on wildcard subscription. For example if we use prefix "updates.*" for wrpc::transport::nats::Client, and then generating bindings using wit_bindgen_wrpc::generate, there is no context about reply subject in handler, only thing we have is nats headers. As workaround maybe instead of nats headers in server handler use struct NatsContext { headers: Option<async_nats::HeaderMap>, prefix: String, ... } with extracted prefix from nats subscription reply subject
