To improve the user experience of `rad init`, the events listener waits for
upload-pack messages indefinitely. The spinner reports back the upload progress
over time.
This process can be cancelled via Ctrl+C without affecting the announcement,
since that is happening in the background.
To also improve the experience, the remote NIDs that have successfully synced
are reported to the terminal.
