Decay hypotheses on each image

Instead of each observation
Simplify path for testing
Correct servo feedback interval checking
Hook executive to unfiltered points
Tweak pixel location for pre-cached sample
Ensure comparison is for float
Tweak visual servo hysteresis
Use tf from image capture time in ray_to_points
Catch early exit case on waiting tasks
Correct transform timestamp on initial pursuit point
Correct duration test again
fix typo
Really fix it this time
Adjusting grab angle and torque
Shrink maximum allowed detection size
Better task cleanup, wait for search image
Tweak sample detector sizes
Ensure headers are copied into new messages
Add marker output to detector
Always announce wait_for_sample exit
