* refactor existing motion detector

* implement and use cnt bgsub

* pass fps to motion detector

* create a simplified motion detector

* lightning detection

* update default motion config

* lint imports

* use estimated boxes for regions

* use improved motion detector

* update test

* use a different strategy for clustering motion and object boxes

* increase alpha during calibration

* simplify object consolidation

* add some reasonable constraints to the estimated box
