I could support but figured its best to keep this logic simpler until thats needed... if you want mixDistribution(Long.MIN_VALUE, Long.MAX_VALUE) we need BigInteger to handle this...

int[] array, indexes;
if (domainSize > 200) // randomly selected
{
int numBuckets = 10;

when it comes to randomWeight and zipF having larger arrays doesn't make too much sense, so this puts a bias into a smaller array and generates values within that section of the range.

I could make this a config, but I didn't need so can refactor later if needed

this is kinda duplicated in org.apache.cassandra.utils.RTreeTest#test but has better coverage... I wrote this class first and feel its always best to have tests at this level / project rather than depending on the C* test...

we actually don't compile on jdk8... so this just makes it so we can use JDK 11 features again
