/// In some instances, we want to combine the values of a concept for several cells into a single concept for
/// a single cell (e.g., when mosaicking multiple cells into a chip with one "cell").  This function averages
/// the values of various concepts:
/// - CELL.GAIN
/// - CELL.READNOISE
/// - CELL.EXPOSURE
/// - CELL.DARKTIME
/// - CELL.TIME
/// For other concepts, it ensures the values are consistent:
/// - CELL.READDIR
/// - CELL.TIMESYS
/// - CELL.X0, CELL.Y0
/// And for others, it takes the "worst" possible value:
/// - CELL.SATURATION
/// - CELL.BAD
/// These concepts are only handled if the cells are all the same cell (mosaicking vs stacking):
/// - CELL.X0, CELL.Y0
