The upgrade of the `radicle-crypto` crate was missed when upgrading
semver versions.
Unfortunately, since it is at the base of the dependency tree, all
crates that depend on it require an additional upgrade.
Mostly changes of `use`s and moving components to `radicle-protocol`,
with the goal of just getting `radicle-node` to work on top of the new
`radicle-protocol` crate.
