Add a new status enum, FrameStartup, used to denote that even though the frame has been successfully captured, the IQ parameters set by the IPA will cause the frame to be unusable and applications are advised to not consume this frame. An example of this would be on a cold-start of the 3A algorithms, and there will be large oscillations to converge to a stable state quickly. Additional, update the definition of the FrameError state to cover the usage when the sensor is known to produce a number of invalid/error frames after stream-on.
