Make the decompose iterator avoid buffering elements past a starter. #64

Closed sunfishcode closed 3 years ago

sunfishcode commented 3 years ago

Once the decompose iterator sees a starter, it should immediately start returning characters from the preceeding sequence. If the input happens to be stream-safe, it should never get more than MAX_NONSTARTERS + plus boundary values ahead of its inner iterator.
