This is a large change that introduces transport encryption via
a Noise_XK handshake. The inner `Service` now works directly
with `NodeId` and doesn't need to interact with socket addresses.
The transport logic takes place in `wire::transport`, and the
established sessions are passed down to `Service`.
Note that the i/o implementation in the `poll-reactor` crate still
needs testing, and there is still work to be done to integrate the
Git transport as part of this architecture.

In interactive (user) contexts, use `try_sign` instead of `sign`.
We also revisit the `Profile` by adding a `signer` method that can
fail, eg. if we couldn't connect to ssh-agent.
Finally, we replace `UnsafeSigner` with `MemorySigner`, which makes
use of `ssh::Keystore`.

The crypto types are useful to use in other components that are
separate from the radicle crate, e.g. the incoming radicle-cobs
crate.
Separate out the types into a radicle-crypto crate. This crate defines
the usual PublicKey, SecretKey, and Signature types. It also provides
the ssh functionality, under the `ssh` feature. It is also necessary
to provide the `From` impl for `Component` here, which again is
guarded by the `git-ref-format` feature.
The `Arbitrary` implementation are moved. The arbitrary decision of
redefining `ByteArray` in both radicle-crypto and radicle was made.
