x/exp/rand was being used for no apparent reason; use math/rand.
x/exp/maps and x/exp/slices can be replaced with maps and slices
respectively now that we require Go 1.23 or later.
Note that the APIs are slightly different due to iterators.
Without hardening, obfuscation is vulnerable to analysis via symbolic
execution because all keys are opened, and it is easy to trace their
connections. Added extendable (contribution-friendly) hardening
mechanism that makes it harder to determine relationship between key and
execution block through key obfuscation.
There are 2 hardeners implemented and both are compatible with literal
obfuscation, which can make analysis even more difficult.
