-------------------------------------------------------------------
bq. the dual checksum fields in CRAR are a bit clunky; the approach of
instantiating the correct one in the constructor that you use in CIS is cleaner.
My concern was the instance would be re-used across multiple sstables therefore
should be chosen per buffer. Is that not the case?
