Deprecating this plugin

[InSyncWithFoo]

As I have partially explained in #57, I intend to deprecate this plugin and migrate all of its features to its sister.

I have been maintaining them for about 4 months now, and the experience so far is not quite good. Repeating almost everything twice is terribly tedious. I know I have made a mistake publishing them both. I know I should not ask my users to waste their time on something which should have been done without them noticing. I'm sorry.

To fix this problem, I'll merge them into one and archive this repository for good. Users should migrate to the new plugin going forward. Until that becomes a reality, I'll continue to keep this plugin alive. There will be no other major releases.

In case someone wants to keep using this plugin, releases from v1.0.0 and later will be installable on 2024.1 and all later versions, regardless of whether they are truly incompatible or not.
