Your code seems a little more complicated, but should work too.  It
would mean that if the parent SeqRecord's seq property was altered,
the per-letter-annotation dictionary would know the new length.  This
is better - but if someone did change the parent SeqRecord's seq, then
perhaps we should also automatically clear the per-letter-annotation?
We could do this by using a full property for the seq attribute, which
would also us to clear any existing per-letter-annotation by replacing
it with a new restricted dictionary using the new length.
