Philippe Teuwen 83e083100b Bring LZ4 support for hardnested tables ...

Testing perfs on an old 8-core laptop:
BZ2   :   2 Mb, average decompression time: 5514 ms
LZ4 -9:   9 Mb, average decompression time:  837 ms
RAW   : 704 Mb, average decompression time:  368 ms

Other LZ4 options don't help: -1 is slower and bigger, --favor-decSpeed does not do anything

To enable:

apt install liblz4-dev
cd client/resources/hardnested_tables
for i in *bz2; do bunzip2 $i; lz4 -9 --rm ${i%.bz2}; done
