While vanilla binary exponentiation with a compiler-generated fast modulo trick requires ~170ns per `inverse` call, this implementation takes ~166ns, going down to ~158ns we omit `transform` and `reduce` (a reasonable use case is for `inverse` to be used as a subprocedure in a bigger modular computation). This is a small improvement, but Montgomery multiplication becomes much more advantageous for SIMD applications and larger data types.
