Upgrade to Kinetic 5.10

This upgrade enables a couple of interesting features:

- [x] full npm-based workflow
- [x] scrubbing and seeking events
- [x] namespaced events (`user_seek.overview`, `user_seek.zoomview`, `user_seek.*` etc.)
- [x] all the performance and bugfix improvements brought by Kinetic since version 4.5
- [x] fix the zoom issues in tests
