The kafka producer decorator doesn't seem to read the record's headers for a span context to become the child of when they exist. This came up when trying to set up distributed tracing through debezium using the outbox pattern where the span context is sent across system boundaries first as a serialized field in the outbox table then injected into the debezium record which is then produced with a standard kafka producer.

you can see this sort of context propagation in the opentracing instrumentation for kafka clients here but i'm not seeing the same kind of propagation from the datadog kafka decorator. I can see it injecting the context of it's current span here but that doesn't attempt to read the headers before doing so.

Am I missing something here? an option somewhere? thanks y'all!
