The `[T]` and `[I]` are interpretted as links when running `cargo doc`. This
table is surrounded in a code fence to prevent this, but also provide a better
view of the table when rendered to HTML.
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.
