Fintan Halpenny 5b4cbc2cd8 radicle: introduce announcer
Similar to the `Fetcher` sans-IO approach, an `Announcer` sans-IO approach is
introduced. The previous `Handler::announce` was already quite close to using a
sans-IO approach, but using internally held state. This change makes the
business logic more reusable – and testable.

Similarly to the `Fetcher`, the `Announcer` is configured and then driven by
telling it when nodes have been synchronized with. It will continuously check if
it has reached its target, yielding to the caller to decide whether to keep
going. In contrast, it also provides a way to mark the process as timed out,
since announcing relies on waiting for events to come back in a timely manner.

When contributing to another's project, it is common for the contribution to be of many commits and involve a discussion with the project's maintainer. This is supported via Radicle patches.

Here we give a brief overview for using patches in our hypothetical car scenario. It turns out instructions containing the power requirements were missing from the project.

$ git checkout -b flux-capacitor-power
$ touch REQUIREMENTS

Here the instructions are added to the project's REQUIREMENTS for 1.21 gigawatts and committed with git.

$ git add REQUIREMENTS
$ git commit -v -m "Define power requirements"
[flux-capacitor-power 3e674d1] Define power requirements
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 REQUIREMENTS

Once the code is ready, we open a patch with our changes.

$ git push rad -o no-sync -o patch.message="Define power requirements" -o patch.message="See details." HEAD:refs/patches

 * [new reference]   HEAD -> refs/patches

It will now be listed as one of the project's open patches.
