by default "client" is on so that it works like before but it's possible
to cherry pick features out and (for example) only build the grpc proto
structs
basically send increments a counter and we compare that before
transforming operations, allowing to stop processing, undo and try to
receive again. This won't solve all issues but should make them much
more rare? I hope
added Default derive to TextChange, added docs for poll and try_recv
methods, implemented new functionality in controllers, using a watch
channel (or reusing if available). Fixed global being always active and
wrongly imported when inactive.
working on this was really hard, so i'm making simple things first.
removed almost everything except bare buffer changes, and not even done
in a smart way, but should be a working PoC? now trying to make a
working client to test it out and actually work on a real prototype
