This module deals with storing a Datadog.DataStreams.Pathway in process, so it can be propagated later on. In Golang, this is handled via Context which is a grab bag that is passed down the whole calling stack. We don't have an equivalent in Elixir, so we instead piggy back off of OpenTelemetry.Baggage. This essentially lets us do the same thing without needing to manually pass data down the calling stack.

This is optional. If you do not have Open Telemetry installed or setup, functions here will not propagate the Pathway. You will need to manually propagate it in your application.
