Use the Xoshiro128StarStar class to represent a pseudo-random number generator that uses the Xoshiro128** algorithm by David Blackman and Sebastiano Vigna.

This generator has a period of 2¹²⁸ - 1 and passes all statistical tests. It is a modern, fast, high-quality 32-bit generator suitable for general-purpose use.

The "**" scrambler makes it suitable for general-purpose use including integer generation. For floating-point generation, consider using Xoshiro128Plus.

Performance: This generator is one of the fastest high-quality 32-bit RNGs available, with excellent performance on modern CPUs.

Use cases:

• Default choice for high-quality 32-bit random numbers
• Applications requiring fast generation with good statistical properties
• Parallel computing with jump-ahead capability
