A moving average of daily highs
A smoothed temperature line replaces each value with the average of a window of consecutive days. Write moving_average(values, window): return the mean of every run of window consecutive values, starting with the first full window. A window that doesn't fit gives []; a window smaller than 1 is a mistake: raise ValueError.
