[racket] FW: q about code for partitions

I have made a new vector version using zero? instead of exact-zero?.

To give users a chance to remove the cache after doing partitions calculations,
I have added set-partitions-cache.

   Code:
   https://github.com/soegaard/racket/blob/patch-14/pkgs/math-pkgs/math-lib/math/private/number-theory/partitions.rkt
