Allow disabling Castagnoli compression optimization
Faster symbol hashing has a positive impact on data compression speed
(around 20% on Intel and 36% on Arm Cortex big cores).
A misfeature is that the generated compressed output will differ from
vanilla zlib (even though it is still valid 'DEFLATE-d' content) and in
some cases has slightly better compression ratio.
We offer here a way to disable the optimization if there is the expectation
that compressed content should match when compared to vanilla zlib.
