entropy fixes and overhaul
fix race condition
splitmix64 has a race condition. it likely (usually) doesn't matter all that much, essentially skeeto references a pointer to the instance of splitmix64 directly during the PRNG's regular churn.
in terms of the random values this seems fine, but i missed it because i wasn't using t.Parrallel(). Downstream packages compiled with the race detector of course threw traces.
the fix involves implementing a sync.Pool of splitmix64 pointers without breaking the existing API. it doesn't seem to slow things down, in fact if anything it seems to speed up operations and reduce allocations (go figure).
performance
besides the above prng pool, the random string generators have been overhauled, and their performance has dramatically increased in all areas.
look at this shit;
