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 tracking command was tracking a project when it should
have been tracking peers.
We also add the ability to pass an alias when tracking from
the CLI.

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.

Send the node's configured external addresses instead of its listenning
addresses. External addresses are ones which the service is reachable
from the outside world, the listening addresses can be the wrong context
(local area network, or 0.0.0.0).

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.

Try having a number of outbound connections to other Radicle nodes at any
given time. The number has been defined earlier as TARGET_OUTBOUND_PEERS.
All network nodes are treated equally, there is no preference.
Attempts to keep connected happen at set intervals (IDLE_INTERVAL) or when
a node disconnects.

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

Its easy to confuse what/who 'node' or 'session' is.
Rename session to 'relayer' to convey its role as message propagator.
Rename the announcement's node to 'announcer', clarifying its as the
source.

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 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.

Since we now have three announcement message types, we need at least
three timestamps per peer. But even that is not enough, since we don't
want to conflate ref announcements for different projects with each
other.
The solution is to also keep a map of timestamps per peer, for each
tracked project. That way we are able to know when a ref announcement is
interesting to us or not.

To build an address book, peers communicate via gossip, sending
`NodeAnnouncement` messages.
These need to be handled by storing the addresses in an address book
and the addresses need to be persisted to disk.
Node announcement messages should also be relayed to peers like other
gossip messages.
