Constructs a new instance of the pseudorandom number generator.

Usage
rng_obj = new RNG();

Description

The RNG constructor initializes a new instance of the Sphere random number generator, seeded based on the current time and date. Unlike Math.random() which uses a very basic linear generator, Sphere uses the xoroshiro128+ algorithm, providing games with a very high-quality source of pseudorandom numbers.

To control the initial state of the generator, use RNG.fromSeed() or RNG.fromState().
