Add fields for minimum and maximum line length duration to the CameraMode structure. This replaces the existing lineLength field. Any use of the existing lineLength field is replaced by the new minLineLength field, as logically we always want to use the fastest sensor readout by default. As a drive-by cosmetic change, split all fields in the CameraMode structure into separate lines.
