script: Recompress strings using LZO whilst binding traces
Try using the lighter-weight LZO decompressor in an effort to speed up
replays (at the cost of making the bound traces slightly larger).
Presuming that with the slight increase in file size (from -1% to +10%),
the file data remains in the readahead buffer cache, replays see a
performance improvement of between 5-10%.
