feat(client): add subscribe_with_options

This commit adds a new method, subscribe_with_options to
komorebi-client.

The first option introduced is to tell komorebi to only send
notifications when the window manager state has been changed during the
processing of an event.

This new subscription option is now used with komorebi-bar to improve
rendering and update performance.
