plugin XEP-0033: code modernisation, improve delivery, data validation: - Code has been rewritten using Pydantic models and `async` coroutines for data validation and cleaner element parsing/generation. - Delivery has been completely rewritten. It now works even if server doesn't support multicast, and send to local multicast service first. Delivering to local multicast service first is due to bad support of XEP-0033 in server (notably Prosody which has an incomplete implementation), and the current impossibility to detect if a sub-domain service handles fully multicast or only for local domains. This is a workaround to have a good balance between backward compatilibity and use of bandwith, and to make it work with the incoming email gateway implementation (the gateway will only deliver to entities of its own domain). - disco feature checking now uses `async` corountines. `host` implementation still use Deferred return values for compatibility with legacy code. rel 450

=======================================================
pubsub/attachments: (Un)Attach Metadata to Pubsub Items
=======================================================

``attachments`` is a subcommand grouping all pubsub commands related to "pubsub
attachments" specification.

With them, you can (un)attach data to any pubsub item. This is notably used to handle
data like saying if an item is (un)noticed, or add emoji reactions.

get
===

Retrieve a list of all attached data to an item.

By default all attachments of the item are returned, this can be filtered by using ``-j
JIDS, --jid JIDS``

example
-------

Louise check all attachments on her last blog post::

  $ li pubsub attachments get -s louise@example.org -n urn:xmpp:microblog:0 -i some-news-acf0

set
===

Update or replace attachments. By default new attachments are updated, but if the ``-R,
--replace`` is used, new attachments replace the whole former one where it make sense. For
instance, ``-R`` doesn't change anything for ``noticed`` attachments, but it will replace
all reactions (potentially with no reaction at all), where the default behaviour is to
merge former and new reactions.

Note that only specified attachments are affected, if unknown or unspecified attachments
exist, they will stay unmodified.

For now, only ``noticed`` (to say that an element has been seen and taken into account)
and ``reactions`` (emojis to show emotion or other kind of reaction about something) are
managed.

``-N [BOOLEAN], --noticed [BOOLEAN]`` takes on optional argument to say if the item is
noticed or not. If the optional argument is not specified, if will be the same as if the
``true`` value was used.

examples
--------

Pierre wants to indicate to Louise that is has seen and he took into account her last blog post::

  $ li pubsub attachments set -s louise@example.org -n urn:xmpp:microblog:0 -i some-news-acf0 -N

Louise wants to react to Pierre blog post about night trains::

  $ li pubsub attachments set -s pierre@example.net -n urn:xmpp:microblog:0 -i nigh-train-are-great-f120 -r 🚆🌜💤
