Changes:

- Added: RandomGenerator support (Java17), though requires self
compilation
- Added: Optimizations for HashUtils next power of function.
- Added: toArray() now returns a cached empty array if the collection is
empty.
- Added: toArray function for AsyncBuilder
- Updated: SCG to version 1.2.2
