Jellyfin/Emby: Check partial sync support

[luigi311]

• add is_partial_update_supported method to each class to validate given version against earliest known supported version
• add get_server_version to get server version number
• add update_partial parameter to user update function, deciding whether or not to allow partial updates

@awakenedhaggis can you take a look at this. I cherrypicked your commit but looks like it lost you as the author. Can you make a PR with a commit similar to this that way it marks you as the author. I rebased it on main and used packaging version to handle the version checks instead of manually checking it.

looks like i had some typos in the original implementation so it should be good to go now. Can you clean with whitespace on your commit, if not ill clean it up afterwards since im going to clean up a lot of the formatting issues

Hi @luigi311 ! Is there any specific style guides you want to follow? I can set up a config for black or your preferred formatter

[luigi311]

i want to switch over to using ruff but ive just been using the default black options for now.

On my end looks like all the author lines were preserved! Might be better to keep this PR so it credits your lines properly

I think unless theres anything glaring here there can be a separate PR for global formatting changes, to keep the change history a bit cleaner if anything
