The only difference betwenn the two traits is the additional Send bound. We should unify this again using the trait-level impl trait feature once it's stable.

Adds a
merge_external_eventsmethod that allows to merge an external event stream, e.g. from the dora-ros2-bridge. This allows waiting for multiple event streams at once without spawning any background threads.We cannot use generics for methods exposed to Python, so the
merge_external_eventsmethod requires an argument of the newExternalEventStreamtype. This type wraps aBox<dyn Stream>and is thus non-generic. Downstream crates need to use this type to allow event stream merging in Python.
