Switch `futures::executor` to Tokio runtime

Use the Tokio runtime we created to run the blocking async tasks.

Trying to set this up so I can get results back from the spawned tasks,
but I'm currently having trouble working out how to extract them from
the async task and return them from `run()`. I suppose I could just
print out the errors directly in that `while let` loop, but ideally I'd
like to return all errors from `run()` rather than printing in `run()`.
