Syndace 75ae8160ae plugin XEP-0384: Fully reworked to adjust to the reworked python-omemo:
- support for both (modern) OMEMO under the `urn:xmpp:omemo:2` namespace and (legacy) OMEMO under the `eu.siacs.conversations.axolotl` namespace
- maintains one identity across both versions of OMEMO
- migrates data from the old plugin
- includes more features for protocol stability
- uses SCE for modern OMEMO
- fully type-checked, linted and format-checked
- added type hints to various pieces of backend code used by the plugin
- added stubs for some Twisted APIs used by the plugin under stubs/ (use `export MYPYPATH=stubs/` before running mypy)
- core (xmpp): enabled `send` trigger and made it an asyncPoint

Implementation of the date and time profiles specified in XEP-0082 using Python's
datetime module. The legacy format described in XEP-0082 section "4. Migration" is not
supported. Reexports of the functions in :mod:`sat.tools.xmpp_datetime`.
This is a passive plugin, i.e. it doesn't hook into any triggers to process stanzas
actively, but offers API for other plugins to use.
