Shot Viewer: sequence field, cameras named CAM_sq0000_sh0000

The Shot Viewer panel gets a Sequence number, saved with the scene. New
shot cameras are named from it with SHOT_CAMERA_NAME_FORMAT
("{prefix}{sequence}_{shot}") and SEQUENCE_NAME_FORMAT ("sq{:04d}"),
both overridable in the config JSON.
