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.

Use the BoundedVec to limit the supported number of refs in
RefAnnouncement messages. The size (235) is the maximum supported by
message wire size.
To reduce the complexity of the changes, BoundedVec is used again
instead of using a new bounded Refs or BTreeMap. This requires
defining new Decode/Encode logic for Ref's element types, and
workarounds for arbitrary instances.

The latter is a fork of the former, which adds const generics
and a bunch of other quality of life improvements that aren't
in the original crate due to it being unmaintained.

Restrict message size decoding by limiting Message's vector size.
Introduce the BoundedVec type to do this on the type level for
convenience and clarity.

Avoid wasting persistent memory by cleaning up stale routing entries
when the routing table is considered constrained. Limit pruning to
improve resiliency in the face of long intervals between service
downtimes.

Keep the node's understanding of project hosting location current by
updating how Inventory Announcement messages are processed.
The Inventory Announcements contain a node's entire listing of projects.
Replace the routing table information for the announcer with those from the
message.

Include the node's IP address in the Node's announcements. Source it
from the service's configuration which can assumed to be populated with
default values when available.

To support ssh-agent, add a signing method that can fail.
Also cleanup usage so that we always accept signer references.

We implement a small proof-of-work on the node announcement message
to prevent the routing table from being filled by fake entries.

Rename the module to session from peer to be consistent with recent
renaming of the type from Peer to Session. Remove stutter by renaming
session::SessionState to session::State, and session::SessionError to
session::Error.

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.

The changes in this commit are all intertwined and it was hard to
split them into smaller commits:
* Use custom transports everywhere
Instead of `file://` and instead of using a child process for fetching
and pushing; we go through our custom transports, which use the `rad://`
and `heartwood://` schemes.
* Introduce a 'mock' remote transport
To test the remote transport without needing to spawn TCP streams,
we add a mock transport that works between storages on the file
system.
* Get rid of node's `git-url`
Instead of git urls, nodes simply use their node-ids to replicate.
This type that was wrapping `Message` isn't very useful here.
If we decide that we do need something like that, it's best handled one
layer below.
