W. Felix Handte 2ca7c69167 Fix CDict Attachment to Handle CDicts with Non-Zero Starts 
CDicts were previously guaranteed to be generated with `lowLimit=dictLimit=0`.
This is no longer true, and so the old length and index calculations are no
longer valid. This diff fixes them to handle non-zero start indices in CDicts.
