Compression level can be specified in parameter level. At the moment,
only level 1 and level 2 are supported.
Level 1 is the fastest compression and generally useful for short data.
Level 2 is slightly slower but it gives better compression ratio.
Note that the compressed data, regardless of the level, can always be
decompressed using the function fastlz_decompress above.
