Add hocuspocus.

👍 Looks good in principle. However, as long as this feature is experimental, it's not sensible to always start hocuspocus only for it to do nothing.

I suggest to remove the definition from the docker-compose.yaml and add a hocuspocus.yaml containing its definition.

If people do want to use it then they can simply add that definition like

docker compose up -f docker-compose.yaml -f hocuspocus.yaml

It would be good to add a mention of this to the README as well explaining how to turn on (and use) this experimental feature.
