Now that the rkisp1 is well synchronized, we can safely increase the
regulation speed and reduce the number of startup frames.  With current
settings, the results based on the stats for frame 0 are active on frame
5. Setting the startup frames to 7 leaves room for one additional lost
frame.

While at it, format the code in a checkstyle compatible way.
