Description

SessionRunner.send_update() does not have handling for generation of multiple Update messages if the full list of originated routes would cause the size of the UpdateMessage to exceed the max size. This should be added and tested (probably along with support for RFC 8654)

Research direction

Start at SessionRunner.send_update() and trace how originated routes are assembled into an UpdateMessage. Review RFC 8654 alongside the existing BGP update-size handling, then add coverage for originated routes that exceed the maximum update size. Done means the routes are split across multiple Update messages and the relevant tests pass.
