Optimize segmentwise recompression

With the recent change to compression schema, we can optimize
segmentwise recompression and target only batches which are
affected to be recompressed or compress tuples which don't
belong to any batch without any decompression. This means
narrowing down the amount of that we need to decompress
and recompress, ultimately speeding up the operation and
generating less bloat in the compressed chunk.
