Add check for too-long words

It's possible for a word within an otherwise-valid wordset to be longer than the size of the board. This breaks everything, and such cases should raise an exception early-on and terminate. See here:

> python make_puzzle_v2.py caligraphy --packing-constant=1.1 --strategy=median --optimize-words
