In an effort to reduce the change of version numbers, dependents of
`radicle-node` should not need to know about the modules:
- `control`
- `wire`
- `worker`
These are internal to the `radicle-node` running, and none of its dependents
accessed them.
This resulted in removing two unused type aliases.
What made the issue fixed in the parent commit harder to spot
for me was the multitude of concepts and terms involved in
encoding: What's *serializing* vs. *encoding*? Why is there
this odd `Frame::to_bytes`?
So I decided to clean up a bit. I removed `fn serialize` so that the
logic stays close to the data, and instead of it provide
`fn encode_vec` in `trait Encode` so that we don't add up with
one-offs like `Frame::to_bytes` again.
Also we make use of `encode_vec` in the tests.
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.
