[FanzyZones] Zone activation based on zone center (#11361)

* Started work on algorithm to select the zone with the center closest to the cursor.

* Fixed algorithm to compute center of rectangle

* Revert to taking the smallest area when the centers are too close (75 pixels).
Temporary turned off buffer of window selection to better see how the algorithm is working.

* Remove change to sensitivity radius.

* Changes in response to SeraphimaZ's comments.

* spelling fix
