When invoked with --optimize, this represents the sample to exceed.
--optimize= : find parameters to maximize compression ratio given parameters
Can use all --zstd= commands to constrain the type of solution found in addition to the following constraints
cSpeed= : Minimum compression speed
dSpeed= : Minimum decompression speed
cMem= : Maximum compression memory
lvl= : Searches for solutions which are strictly better than that compression lvl in ratio and cSpeed,
lvl= : Searches for solutions which are strictly better than that compression lvl in ratio and cSpeed,
stc= : When invoked with lvl=, represents percentage slack in ratio/cSpeed allowed for a solution to be considered (Default 100%)
: In normal operation, represents percentage slack in choosing viable starting strategy selection in choosing the default parameters
(Lower value will begin with stronger strategies) (Default 90%)

tries= : Maximum number of random restarts on a single strategy before switching (Default 5)
Higher values will make optimizer run longer, more chances to find better solution.
memLog : Limits the log of the size of each memotable (1 per strategy). Will use hash tables when state space is larger than max size.
Setting memLog = 0 turns off memoization
