CoAP is the transport for links where MQTT is more than the budget allows: it
runs over UDP, its headers are a handful of bytes, and a node can fire a
reading and forget it rather than holding a session open.
The reliability choice is re-exported as a runtime Reliability
object, because the generated enum is types-only.
Ergonomic facade over the generated CoAP binding.
