* Accept iterables as inputs to backend methods
* Shift add-on check to backend; use new endpoint
The new endpoint will return info on a suitable branch if found,
instead of returning all branches. This simplifies the frontend code,
and means that you can now drop support for certain versions without
it also remotely disabling the add-on for people who are running one of
the excluded versions, like in

* Bump version to 23.09
This changes Anki's version numbering system to year.month.patch, as
previously mentioned on https://forums.ankiweb.net/t/use-a-different-versioning-system-semver-perhaps/20046/5
This is shaping up to be a big release, with the introduction of FSRS and
image occlusion, and it seems like a good time to be finally updating the
version scheme as well. AnkiWeb has been updated to understand the new
format, and add-on authors will now specify version compatibility using
the full version number, as can be seen here:

* Shift update check to backend, and tidy up update.py
* Use the shared client for sync connections too
pytest will show what differs in simple assert statements
concurrent mode is supported with a plugin, but like nose2, concurrent
mode hides the cause of import errors, so I've left it off for now.
