Autotracking bugfixes and zooming updates (#8103)

* zoom in/out in search for lost objects

* predicted box should not be empty

* clean up and update zoom logic

* only zoom if enabled

* more cleanup

* check for valid velocity when zooming

* only try absolute zoom in if obj area has changed

* zoom logic

* don't enqueue lost object zoom if already at limit

* don't disable motion boxes during ptz moves

* velocity threshold based on move coefficients

* fix area zoom logic

* disable debug zoom

* don't process objects if ptz moving

* recalc with exponent

* change exponent

* remove lost object zooming

* increase distance threshold for stationary object

* increase distance threshold constant

* only zoom out if nonzero

* camera name in all debug logging

* add camera name to debug logging

* camera variable name consistency

* update calibration behavior and docs

* docs and better zooming

* more sensible target values

* docs wording

* fix velocity threshold variable

* zooming tweaks and remove iou for current objects

* debug and docs

* get valid velocity

* include zero

* additional debug statements

* add zoom hysteresis

* zoom on initial move if relative

* only update target box if we actually zoom

* merge dev

* use getattr instead of get

* increase distance threshold

* reverse logic

* get_camera_status after preset move to store zoom

* final tweaks and docs

* use constants and catch possible debug exception

* adjust zoom factor exponent

* don't run motion estimation when calling preset

* adjust dimension threshold

* use numpy for velocity estimate calcs

* more numpy conversion

* fix numpy shapes

* numpy zeros dimension

* more zoom out conditions

* fix velocity bug

* ensure init has been called in debug view

* ensure onvif init if enabling by mqtt

* change default hysteresis values

* recalc relative zoom value

* zoom out value

* try to zoom when object isn't moving

* try zoom when tracked object is not moving

* don't try to zoom every time

* negate zoom out condition when needed

* hysteresis constants for absolute zooming

* update zoom conditions

* don't recalc target box on zoom only

* zoom out if above area threshold

* don't print zooming debug for stationary obj

* revamp zooming to use area moving average

* zooming tweaks and expose property

* limit zoom with max target box

* use calibration to determine zoom levels

* zoom logic fix

* docs

* add tapo c200 camera

* fix initial absolute zoom

* small zoom logic fix

* better invalid velocity checks

* fix test

* really fix test this time
