> LazilyCompactedRow.update doesn't add the CFInfo or columnCount to the 
> digest, so the hash value in the Merkle tree does not include this data.  
> However, PrecompactedRow does include this.  Two consequences of this are:
> * Row-level tombstones are not compared when using LazilyCompactedRow so 
> could remain inconsistent
> * LazilyCompactedRow and PrecompactedRow produce different hashes of the same 
> row, so if two nodes have differing in_memory_compaction_limit_in_mb values, 
> rows of size in between the two limits will have different hashes so will 
> always be repaired even when they are the same.
