I ported a number of my pseudo-random number generator implementations from Ruby to Gno, building them be compatible with the standard Rand() implementation, so that any of these can be used as a drop-in replacement for the default PCG algorithm. All of these are faster than PCG, while still having competitive-to-superior statistical properties and predictability resistance. Further, the ISAAC family of generators are cryptographically secure, and when properly seeded, still have no known practical attack vectors.

Revise all of the output to use ufmt.

Tidy gno.mods; add a Sprintf %f test.

…e error?

…intf float formats a bit more to be closer to Go's support.

…r.Error` is used elsewhere.
