Adding a compression level flag to zlib_bench
Optimizations can have different impact depending on the compression
level used.
It is quite handy to be able to change the compression level used for
experiments while optimizing zlib.
This patch adds an optional flag (-compression) to allow passing the desired compression
level (0 to 9). To keep consistency, the user has to pass the target
wrapper format (e.g. -wrapper gzip|zlib|raw).
Finally, a help parameter is now supported (i.e. ./zlib_bench -h | --help) that
will print the expected parameters while invoking the tool.
