After cloning, we show a cool little summary with some repo stats.
We had to make some adjustments to the way visual width is calculated
due to a bug surfaced around emoji width calculation. Unfortunately
there isn't a perfect solution that works across terminals yet, so the
"variation selector 16" code-point is filtered out for now.
This adds functionality so that on `rad sync` and `rad clone`, we
connect to known seeds if necessary, before attempting to fetch.
In passing, some related changes were made:
* The `rad sync` command's arguments were reworked:
`--replicas <count>` can be used to specify a replica count when
fetching
* The `rad patch` command no longer has a `--fetch` option
* It's now possible to tell the node not to automatically connect to
peers in the background
* `AddressBook` is being used underneath `Seeds` to allow for shuffled
iteration
