CameraManager class
A parent isolate that spawns CameraIsolates to manage the cameras.
With one isolate per camera, each camera can read in parallel. This class sends VideoCommands
from the dashboard to the appropriate CameraIsolate, and receives IsolatePayloads which it uses
to read an image from native memory and send to the dashboard. By not sending the frame
from child isolate to the parent (just the pointer), we save a whole JPG image's worth of bytes
from every camera, every frame, every second. That could be up to 5 MB per second of savings.
