protocol: Depend on `cypheraddr` not `cyphernet`

`radicle-protocol` depends on `cyphernet`, but only uses the module
`cyphernet::addr`, which is a re-export of `cypheraddr`, which is
unnecessary (as `cypheraddr` alone would do), and invites accidentally
pulling in more dependencies via `cyphernet`.

To prevent accidentally depending on further types from `cyphernet`,
change this to more conservativeley depend on `cypheraddr`.
