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.
Prepare the crates for releasing to crates.io:
- radicle-remote-helper: 0.10 -> 0.11
- radicle-term: 0.12 -> 0.13
- radicle-cli: 0.13 -> 0.14
- radicle-node: 0.11 -> 0.12
- radicle-fetch: 0.11 -> 0.12
- radicle: 0.15 -> 0.16
It was also necessary to specify the `version` in the workspace Cargo.toml file,
since this is required for publishing to crates.io.
