Don't update blake3 version, otherwise it results in

```
Updating constant_time_eq v0.2.5 -> v0.3.0

error: package `constant_time_eq v0.3.0` cannot be built because it
requires rustc 1.66.0 or newer, while the currently active rustc version
is 1.65.0

The following commands are affected:

- `picodata connect [user@][host][:port]`
- `picodata run --peer`
- `picodata run --listen`
- `picodata run --http-listen`
- `picodata run --advertise`
- `picodata expel --peer`

Only `picodata connect` respects the username. Other options just ignore
it.

- Provide new `struct Address`
- Replace `try_parse_address` function with `impl FromStr for Address`.
- Provide both unit and pytests

Picodata treats absent hostname (`:8080`) as `localhost` by default,
which resolves to IPv6 on Mac. The test explicitly specified
inconsistent addresses, and that caused "connection refused" error.
