This enables AAP 2.0 clients to receive status reports with a new ADU flag (as we already deliver BIBE bundles). Moreover, it allows clients to set a report-to EID and sets all of the status report flags on newly created bundles in case a report-to EID is provided. Closes: #241 Signed-off-by: Felix Walter <felix.walter@d3tn.com>
