Adds the serialization half of the deletion vector codec (inverse of DeserializeDV) and a DVWriter that accumulates positions per data file and flushes them as a single Puffin file with one blob per data file. Returned DataFile entries carry ContentOffset, ContentSizeInBytes, and ReferencedDataFile so they can be passed directly to RowDelta.AddDeletes(). Part 1 of apache#997.
