refactor(sensors): Sensor event channel data, resolution tweaks.

* Refactor sensor events to include channel data,
  necessary for prop split encoders, and avoiding duplicate calls,
  to fetch channel data twice, etc.
* More consistent behavior driver API.
* Allow setting triggers per resolution at the behavior level optionally.
