DeltaByteArrayReader has incorrect skip behaviour #1968
Description
When reading delta encoded columns (v2 API) and skipping values the read fails (with differing exceptions). This is because the reader needs the last value but the skip logic is not managing this.
A modified DeltaByteArrayReader which calls readBytes() on skip() does fix the reading. Not sure if there is a more efficient solution possible then simply invoking readBytes().
